Change upper/lower textures to not skew by default, add new linedef flags on normal linedefs:

Browse source 
Effect 1: Restore skewing on upper/lower textures
Effect 2: Disable skewing on midtextures
Effect 3: Flips effect of Lower Unpegged for midtextures only
(Effect 3 w/o LU: midtexture sticks to bottom, bottom texture sticks to
upper edge. Effect 3 w/ LU: midtexture sticks to top, bottom texture
sticks to lower edge.)
