MaxED a31c6b6652 Fixed, Script Editor: resources navigator was always loading the first WAD lump with matching name when trying to open any of several WAD lumps with matching names.
Reverted, Visual mode: looks like all additional cases of displaying sky hack added in r2755 were actually undefined engine behaviors, not the "proper" shy hack... Reverted implementation to the wiki definition of the sky hack.
