Removed a ton of vanilla gfx + other changes

-Cleared all vanilla gfx I could find from gfx folder (traits,
ambitions, interface, etc) also did the same for interface folder
-Moved all MEP trait gfx references to one new file called
traits_mep.gfx so the vanilla file can overwrite on new patches
-If I deleted anything by mistake let me know, if you notice in game etc
