(svn r27729) -Codechange: Do not count static NewGRF when checking for the maximum number of NewGRFs in a game.

-Codechange: Remove LAST_GRF_SLOT and MAX_NEWGRFS. Now NETWORK_MAX_GRF_COUNT is the only constant to specify the maximum number of non-static NewGRF.
-Codechange: Increase the number of file slots, effectively increasing the maximum number of static NewGRF and baseset GRFs.
