undid difficulty patches to the missions, didn't seem to work for some reason

buffed vehicle cannon to tier 4

fixed how the Cauterizer was improperly set to tier 4, and upped the tiers of a couple missions to tier 4 as well

reverted vanilla hiremercenary text and gave Shellguard mercs their own unique version finally, although it's at the cost of compatibility with mods that overwrite the player.lua file

replaced the shellguard airlock door sprites with updated ones made by LoopyZach

because I like to nitpick, the guard mart vending machine now has orange text to it

edited the vanilla hiremercenary text to be applicable for both Penguins and SG mercs
