[1657502] Added use_fake_cursor option to make Crawl draw a cursor for Unix

terminals that cannot draw cursors on black spaces or darkgrey areas. May need some work, since the fake cursor tends to leave artifacts on the scrolling edge.

Removed the +1 X offset to the viewport.

Fixed crash when monster wielding a weapon of orc slaying hits player (Erik).
