Show only PWAD/IWAD textures/Default textures/lightlevels/etc

[TwinBeast]

Show only PWAD/IWAD textures could work like the show only used textures, but this one shows the textures from different wads.

Oh yea, another request. Different default textures/lightlevels/etc for each configuration. Or bring back the ability to use the empty - texture in the defaults...
