- Changed: Textures without a name no longer get added to the texture manager's

hash chains.
- Fixed: specifying texture patches or font characters by full lump name instead
  of texture name didn't work. To do this properly the texture manager needs
  an option to look for a texture by lump number so that such textures can
  be maintained without interfering with regular operation.
- added 'skystretch' and 'autosequences' keywords for MAPINFO so that the effects
  of 'noautosequences' and 'forcenoskystretch' can be cancelled.
- Added a 'gamedefaults' section to MAPINFO after discovering that 'defaultmap'
  gets reset for each MAPINFO. A global section is needed to define a game's
  default setting in zdoom.pk3. The gamedefaults should normally not be changed 
  by PWADs but it can be done if some mod intends to change gameplay settings 
  but wants to allow custom add-ons on its own.
