frosch 210fda2141 (svn r25839) -Codechange: Use NUM_HOUSES_PER_GRF instead of NUM_HOUSES to properly distinguish limits per NewGRF and limits of the pool.
-Change: [NewGRF] Lower the limit of house types per NewGRF from 256 to 255 to prevent usage of ID 0xFF in Action3, and thus allowing it to become an extended byte somewhen.
