Fixed late loading in SprayManager.
Added the ability to target specific clients/groups in sm_removespray.
Fixed a bug in sm_spray caused by not checking for
ProcessTargetString()'s return for negative values. (smh)
Spray lifetime is now reset when sprayed.
Fix "sm_spray" having no admin flag, this was due to previous testing.
Fix bugs caused by NULL_VECTOR not being NULL anymore after being used
in GetAngleVectors() (???)
