While in GZDoom this uses the IWAD name, the same approach is a lot more problematic here because of name duplications with far more incompatible content.
So this allows targeting a group of base games instead of one specific version.
* Initial implementation from d32dcd5f8e was not working properly and already had some workarounds for when the player was underwater, etc.
* Re-read implementation in GDX and rebased off of it.
* Fixes#303.
Parts of the sound system treat entry 0 as "no sound" so nothing placed there would play.
This made the one custom sound in "The Way of Ira" not play because as the last sound being defined it ended up in the first, invalid slot.
0 means 'default', -1 means 'silent'. This caused playback issues for useSoundGen. All other places were passing proper volume values along, this is the only one to read the volume from map data.
Blood needs this for its PlayerSound controller, which is run right on map load - so without this it wouldn't start the sound when a map is initiated from the console.
Aside from not having been functional, this is ultimately more harmful than useful as it forces loading of a large number of textures at the same time during gameplay instead of spreading them out.
* made it palette aware
* use backend facilities to track precached data.
* fixes bug in animation precaching loops - they only precached the base index over and over again.
Due to some old code it could happen that these weren't fully set up and missed their translations.
Fixes#301 - Blood's invulnerability palette is identical to the base.

To allow cumulative loading without interfering with other ports, Raze will now look for files called xxxx-raze.def, where xxxx is the default .def name (e.g. duke3d-raze.def for Duke3D.) and if that is found, cumulatively load all same-named files - it will fall back on the default name if no such thing is found.
-def still overrides both and will not cumulatively load.
This was incomplete and just ignored Duke's special music, and the levelnum generation used an outdated formula so that it never managed to assign any music to the maps.
