Christoph Oelckers e77f83fbf6 - Added new Scroll_Wall special to allow more control over wall scrolling.
Since it uses fixed point parameters it can only be used in scripts though.
- Added flags parameters to all wall scroller specials that didn't use
  all 5 args.
- Separated scrolling of the 3 different texture parts of a sidedef.
  While doing this I did some more restructuring of the sidedef structure
  and changed it so that all state changes to sidedefs that affect rendering 
  have to be made with access functions. This is not of much use to the
  software renderer but it allows far easier caching of rendering data
  for OpenGL because the only place I need to check is in the access functions.
