- Fixed: If you called the FString assignment operator that accepts a

const char * with a string inside its buffer, it released the buffer
  before copying the string.
- Added a new FString constructor that creates the string from a lump.
- Fixed: G_DoReborn() calls G_InitNew() with mapname set to level.mapname.
  G_InitNew() then copies it onto level.mapname, which is undefined
  behavior (although it does work as we want it to).
- Modified FMemLump to store its data using FString. That class provides
  a convenient method of storing reference counted data, so now FMemLump
  doesn't need to muck about sneakily using const_casts and possibly
  tricking its users into thinking that an old one is still valid after
  being assigned to a new one.
- Fixed: The IMGZ, PNG, PCX, and JPEG loaders assumed the files were
  large enough for their headers without actually checking.
