Added UTF-8 BOM detection
- This prevents things like the following from happening, by warning the user if an incompatible file is loaded: http://hercules.ws/board/topic/5126-mapname-selft-announcer/?p=33068 - We're erroring out instead of ignoring it, as explained in the source comment. - Special thanks to jaBote.
