Fixed minor script error with ambient object spawning

2.0.2 Engine update
This update of the mod includes a massive rewrite of almost all my internal code, including a custom build modifier spawn engine. The minum version for this mod to work is now 2.0.2 (duo to changes paradox has made)

Changelog:

• A lot of extra tile blocker graphics for vanilla tile blockers
  
• Some extra tile blocker graphics for this mod's tile blockers
  
• A start menu will now ask you with what number of planet modifiers you wish to start with. In multiplayer the recomended setting should be automatically chosen. The planet modifier spawn engine will take a few seconds to spawn everything after you unpause (spread over 2 ingame days).
  
• Not so friendly gaia world. Events for that comming later.
  
• 
  
  

• full rebalance of modidifer spawn chances.
  
• Made some ghost files to stop the error log reporting it cant find all the compatibility planet classes. The error log should be a lot shorter now.
  

• Tons of small fixes to localisation and other issues users have reported.
  
  

- Fixed several code errors
- Fixed colony capital events, they should once again happen
- Fixed several localisation issues

Some fixes for armies and v2.0.2 beta

Added exnihil trigger file for inter-mod compatibility.

* Nerfed precursor mechs a bit. Sorry :<
* Mastery of Nature no longer gives the extra tile blocker techs but instead now also increases the tile blocker clearing time by 33%
* Tile blockers from this mod now only need energy to be cleared
* Slightly lowered the chance for precursor modifiers to spawn at galaxy generation
* Slightly lowered the chance for resource asteroids to spawn at galaxy generation
* Lowered the orbital bombardment bonuses from various modifiers to not make planets immediately immune to bombing. This will continue to be tweaked in combination with planetary shield generators. Expect some kind of cool interaction with colosus too in the future.
* Fixed some localisation errors
* Some more fixes that I completly forgot what they were

Fixed a bug allowing all planets to build precursor bunker command centers

Small bugfix patch:

- Included some missing localisation
- Fixed some localisation mistakes
- You now need to build a star base "precursor shipyard uplink" to make use of a solar system that has a precursor shipyard (modifier on a planet).
- You now need to build a "precursor bunker command center" to make use of precursor bunker armies. A planet with a precursor bunker modifier will allow you to build one of these command centers. The command center will produce 1 bunker defense "unit" automatically every month up to 3. Then it will slowly remove normal defense armies and replace those with bunker units. This is a weird behaviour (the deleting defense armies) but it works in the end. Consider this a bug that "works".
- Planets destroyed by the world cracker should now lose most modifiers. I don't have apocalypse so I cannot test this thoroughly. It's a small script that runs after the planet is destroyed so it does not interfere with or overwrite any vanilla events.
- Increased the build time for precursor mechs and slightly lowered their stats.

2.0 Compatibility update.
Another update is planed to adress any potential bugs and balance issues. I pushed this update live with enough testing for bugs but cannot guarantee if all the new/replaced bonuses work. Please let me know if there are any issues! Thank you :)

Changelog:

• Stars now have a chance to go into an increased or decreased solar cycle giving a system wide energy buff/malus.
  
• Planets now have a chance to experience a meteor shower.
  
• Capital worlds now gain a unique ethic based event chain after a while.
  
• Habitats can now gain a small amount of resources from modifiers found on planets (and their moons) below where the habitat was build. Modifiers text will show if they give a bonus to an orbiting habitat.
  
• 28 new habitat modifiers added.
  
• 1 new black hole modifier added.
  
• 1 new pulsar modifier added.
  
• 4 new stars modifiers added.
  
• 8 new planet modifiers added.
  
  

• Slightly increased spawn chance of modifiers for dead worlds (barren, frozen, etc..).
  
• Tweaked planet rings to be a bit more common and made them look a bit nicer.
  
• Binary asteroids now have a physical twin asteroid.
  
• Planet wonders now have a chance based spawning system so they should be a bit rarer.
  
• Negative habitability maluses from modifiers have been increased a lot.
  
• Some planet bonuses were changed to account for removed bonuses in 2.0 Most noticibly any bonus to border range, sensor range, planet fortifications were removed. Some alternative bonuses were put in place as there are no equivilent bonuses that balance well. Some of these might change in the future.
  
• Mastery of Nature updated to match 2.0 MoN but will also give all the tile blocker clearing techs from this mod only. Vanilla tileblocker clearing techs will still need to be researched. This was done for balance and "fun" reasons.
  
• Armies from this mod have been updated and balanced a bit more.
  
• Precursor mech armies can now leave the planet and attack.

• Fixed beautiful ring world modifier for real this time.
  
• Fixed several rare bugs with planet changes when a crisis conquers/purges them.
  
• Fixed all the bugs that appeared with 2.0 and this mod
  
  

• A particular robot in love still gets disassembled :(
  
• Some precursor modifiers might need balance tweaks.
  
• Unsure if star base bonuses work from a planet. This will neeed more testing.
  
• New events that change planet classes will likely not correctly update the planet modifiers. I'll get those those as soon as I see them.
  
• The capital event chains for machine empires, hive minds empires and xenophile empires still needs to be written. The current story text stuff is placeholder.

Fixed bug with wondrous planets not spawning.
