frontport r8667 

"Rewrite the stupid file transfer routines.
* It will now only send the file to the person that needs it.

* Adds abort code to the file routines as well, and also tries to detect when the Host is using a malformed filename to host a map.

* Make sure user can't hit the 'ready' button when the map transfer is ongoing.

* Get rid of the silly delays (Much faster transfers)

NOTE: we are still capped by fps. 
fixes ticket:1128
fixes ticket:1127
refs ticket:215 (still can't transfer 'map packs')"
