player.c: factor out 2x almost dup'd code preparing hitscan weapon firing.
The code is duplicated with small changes for the hardcoded and custom projectiles. Adding local functions P_PreFireHitscan(), A_PreFireHitscan() and Proj_MaybeAddSpread(). git-svn-id: https://svn.eduke32.com/eduke32@3358 1a8010ca-5511-0410-912e-c29ae57300e0
