- Added all the missing FIFOHEADs in the login/sql servers (required for TURBO support)

- Fixed the fact that the TURBO code breaks when you attempt to handle more than one connection at a time within the same function. However this broke map-server compilation, therefore, don't use TURBO yet! It needs more fixing (and I need more time to fix it)
- While at it, cleaned a few packet implementations in the char/login servers which were not only ugly, but had some really stupid flaws within (stuff like escaping a string, and then using the non-escaped variable to insert to SQL? T_T) And will someone explain me why the TXT servers are coded much more cleanly, and without such horribly broken code as I find in the SQL ones? T_T;
