Fix broken roaming spectator mode

* Added server cvar (mp_freespectatormode) which controls when a player can enter a free spectator mode (orbit cam, or free roaming). 0 = never, 1 = only when spectator, 2 = Always
* Free roaming will now be part of the cycle when pressing the jump key
* The overlay is now toggled with the crouch button
* Strafing in free roaming no longer snaps to different players
* Fixed bug that would break spectating completely if returning to the ready room while in free roam
* You can no longer enter free roaming using the "specmode" and "spec_mode" console commands if it's disabled by the server
