Fix `sv_alltalk 1` (broken originally by respawn changes) (#291)
* fix sv_alltalk 1 (broken originally by respawn changes) * nvm i forgor to commit literally the main file * fix formatting * unsure why this was buidling but it shouldn't've been? fix build errors regardless * remove duplicate alltalk.cpp * add (experimental) potentially less jank patch * (now working) better patch for checking if alltalk is enabled * oops put a z in it boo womp * fixup formatting
