Some minor SFX fixes

[Tesculpture]

These are a pair of patches that fix a couple of issues with vanilla Doom's sound effects. They should be safe to stick in autoload; neither replace any actors and shouldn't conflict with any mods. One does work via ZScript though, so will need modern GZDoom.

They are:
cgun_soundfix - Changes vanilla Chaingun Commados and Wolfenstein SS to use the Pistol/Chaingun firing SFX instead of the Shotgun one. This is done via a SNDINFO edit.

vilefire_soundfix - Uses ZScript to fix the issue mentioned here regarding A_StartFire. Basically, Archvile flame is supposed to have two sound effects; an initial whoomph (vile/firestrt), then the crackling I'm sure we have all learnt to fear (vile/firecrkl). With this fix, the initial missing sound effect will finally work. Note this will also cause any actor inheriting from ArchvileFire to make the sound upon spawning.

Nice! Something you might want to add, I've read on the Cutting Room Floor a sound named DSSWTCHX was supposed to play when deactivating a switch, but doesn't due to a coding issue. Can you fix that?

DSSWTCHX can be heard when pressing a level exit switch, or leaving a menu.

Yes, I know. I'm asking if the feature described in TCRF can be restored.
