SOC_**** lump name support
Exactly what it says on the tin: lumps with "SOC_" prefix now are read as SOC lumps like with MAINCFG/OBJCTCFG. Go nuts.
As a bonus, I've changed things with SOC lump detection so MAINCFG, OBJCTCFG and the new SOC_**** lumps are loaded in the order you find them in WAD files (rather than an arbitrary load-MAINCFG-then-load-OBJCTCFG thing as before). All of these are still loaded after Lua scripts though, mind.
