Read MAPINFO/Skills and add those to the drop down list.

It seems that ZDL is already smart enough to parse MAPINFO/Map in order to provide a list of properly named maps, but it still lacks the ability to do so for skills.

It definitely can be done, though not so easy as with maps. I'll have to replicate what original ZDoom code does with skill definitions, including reading them in correct order (wad by wad), honoring all the clearskills and skill commands, keeping track of skill indexes and replacements.
