Updated method documentation and cleaned up

Method documentation should be completed. Only thing left now is polishing up (fixing typos, update wording, add enumerator data to method documentation that doesn't have it, etc)..

Cleaned whitespaces

Corrected/Fixed up some comments

Removed all known documented method comments in LuaFunctions.cpp. Commented out methods are now marked as undocumented until they are uncommented & documented in their respective header files.

Removed 'Getter, Setter, Boolean, Other' comments in method files

Documented VehicleMethods, the rest of PlayerMethods, UnitMethods, CreatureMethods and GuildMethods.

Refer to #101 for more information
