Also simplified the sound init decision making. With FMod gone there is no reason to be pedantic here. Even the check of snd_backend for the Null device could be omitted here, its only realistic use is '-nosound'.

As nice as the automatic is, this will trigger far too many cases where it will disable translucency for mods that only change some texts. Dehacked is very often only used for non-actor related modifications.
If the automatic is supposed to be the default it needs to do a lot more thorough checks to avoid bug reports due to misunderstanding the feature.
It now works the following way:
(0) - Force off (ZDoom defaults)
(1) - Force on (Doom defaults)
(2) - Auto off (Prefer ZDoom defaults - if DEHACKED is detected with no ZSCRIPT it will turn on) (default)
(3) - Auto on (Prefer Doom defaults - if DECORATE is detected with no ZSCRIPT it will turn off)
