Removal of an unused variable since messagemode code was dropped from SP.
Store the guid in client persistant for future uses.
Fixes previous commit and adds a few minor changes to the clientconnect early code.
Bots is bots.
Moved some things back, while retaining GUID support.
Fixes the ClientConnect log printf and includes guid now.
Adds IP, guid, and name to ClientDisconnect log printf.
Merged ioq3 change that defines all clientslots to be "clientslot" until set otherwise to prevent NULL classname case.
Adds mousewheel support to textscroll boxes. SP and MP.
Removed com_introPlayed cvar.  Was leftover q3 cruft.
Added com_bootlogo cvar that defaults to 1.  Disable to turn off starting movies without having to alter startup parameters.
Fix #254 - no more crashes when calling Com_Error!

Problem was that the game library calling Com_Error was then being unloaded by Com_Error. I had checked this before but obviously not with enough detail. The libraries are now unloaded using a 'delayed free' feature where the libraries are not actually unloaded until after the exception has been caught.
