Sound changes and additions - WIP (oh god please don't merge)

Completely experimental at the minute due to my bare minimum of
knowledge regarding coding. Some people who actually know about this
stuff could help by commenting on fuckups esp regarding MoMMIs, Wizard
teleport, mech sound changes, sound.dm and general things to avoid
doing.

mommi specific voice sound files, several sound bytes it can use e.g.
excuse me, hi, would you like coffee? etc. for general cuteness' sake
added sound to dice roll
added sounds to attacks with tools such as the welding torch, crowbar
etc.
added a beep when plastic explosives are armed
some sounds for slicing weapons changed
new sounds for blob
new sounds for when a changeling violates someone
sounds for the gibber
new explosion sounds added
changed emp sound
changes to dartgun, ebow and syringe gun sounds. More distinct.
more smushy beating sounds and piercing slicey sounds
new shotgun sound
pai startup noise
sound for wizard teleport
new ion rifle sound
whip sound for the chain of command
new staff of change sound
new radgun sound
rejigged SMG sound
detective scanner given a sound
lots of new mech sounds
cult constructs have more fitting attack sounds
new grenade launcher sound
improved(?) chem grenade sound
durand lockdown has a sound and there is a new mech entry sound
staff of change has a new sound to differentiate it from the emitter

This will most likely be a clusterfuck, but i'm putting it here so
people can give me advice or help with it.
