Rearrange things a bit and remove duplication between ParadoxModBuilder and diff_paradox
Partial westernization
Strip UTF8 BOM nonsense before parsing YAML since YAML gem can't handle them.
Return vassal cores CB.
patch_file! should only do something if content changes
Better #localization! interface - old one resulted in very long lines and a lot of code duplication
Extra formable countries
Compare normalised Paradox Mod files
If files differ in normalized mode, diff their normalized forms not raw files
Religions are now fully modded
Peasant war done too, that should be all now :-D
