Add null reference check to avoid null access violation in rare cases during call to GetTreeScale()

Fixed a small bug where keybinding configuration settings file keeps getting deleted

• Fix this mod changing game locale
  
• Added German localization. Appreciation goes to Chameleon!!

Fix Linux pathing file not found exception error.

• Initial Implementation of localization framework
  
• Traditional/Simplified Chinese localization added
  
• Improvement to Tree Resizing framework, now resizing trees are more responsive
  
• Decrease minimum tree scale factor to 0.2 (Larger trees may be shrinked even smaller)
  
• Fix hotkey action to have optional panel checkboxes to reflect current tree snapping state and lock forestry state correctly.

1. Bugfixes to Tree Resizer, where after exiting to main menu and reloading a game causes it not to function correctly.
   
2. Major framework rework on key binding, now its more robust
   
3. Removed all non-essential static variables, major framework rework on Tree resizer so its more memory friendly with .NET GC. (Especially when resizing buffers due to setting custom tree limits)
   
4. This mod now requires less memory footprint.
   
5. Micro-optimization to deserialization process.

Bugfix for Tree Tool
As I was making changes in Tree Snapping functionality for MoveIt mod, I forgot to also make the relevant changes to the default Tree Tool. Now it is further optimized as I gain more experience with C# and Harmony, with the restored function of tree snapping to Props, building, networks and terrain

Bugfixes to version 0.9.5

• I did a micro-optimization within my customized GetWindSpeed where I replaced Mathf.Clamp with xor and shift operation. This apparently does not play well in rare situations, and have reverted to the old way, which is slower but robust.
  
• Fixed a situation where the scaler buffer size is not updated if user shrinks the custom tree limit, causing array index out of range.

• Bugfix in patch to TreeManager::AfterDeserialize. I used the wrong instruction, so C/O original codes are always run regardless of old unlimited tree format. This error is silent, and not apparent to most users, and is fixed now.
  
• New function added to resize trees by pressing 'comma' and 'period' on the keyboard when planting trees or using MoveIt move. MoveIt tool does not support cloning the same size.
  
• Minor adjustment to options UI for clarity
  
• Hotkey binding is now supported.

Tidy options panel, separating Tree Snapping options
Add experimental tree snapping option
introduce tree snapping to buildings, networks, and props.
Some micro-optimization in serialization process

Current experimental tree snapping is not perfect, especially when cloning, so please feel free to test it out and give me feedback in how you feel it should be done
