- Added a missing map_quit in clif_parse which was the real reason for the crashes.

- Therefore, removed the session valid checks from intif.c
- Thanks for Flavio for figuring out how to reproduce the crash. And unthanks to me for introducing it on the first place D:
- Note: Every connection before being closed and free'd will set eof to 1 and invoke the parse function (clif_parse for players), and since this is the last invocation, it is clif_parse's job to do any cleanup necessary. The missing map_quit what did was to leave the player pointer reference in different db's, which lead to a dangling pointer! Which obviously leads to no good. The map server's code should always ensure that session[sd->fd]->session_data == sd ALL the time (except when sd->fd is 0).
- Finally, not writing any of this on the txt changelog file so Flavio can have the glory of the bugfix :B
