* Fixed guild and guild member exp truncation issue (bugreport:4130, since r14242).

- Fixed guild member position, hair, hair color, gender, class and level could potentially become corrupted due to shorts being read as ints (partially since r2986).

 	* Fixed map server getting notified of hair, hair color, gender, class and level changes from a char server (TXT only) twice (since r2986). [Ai4rei]
 	* Fixed saving/loading errors with compilers (such as VC6, MinGW), which do not recognize %ll format (since r14242). [Ai4rei]
 	- This also fixes guild leader name being displayed and saved as "(null)" in the guild member list.
