Fix a portability issue with md_hasclreol(). Some games' implementation of md_hasclreol() poked around in ncurses internals, which does not work for some ncurses build configuration. Most games did not actually call md_hasclreol(), so it was removed. There is a standard terminfo function which can retrieve the value of the clr_eol capability, so this was used for rogue5.
