Fixed event handling. ValGrind fixups.

My yesterday's fix on handling 1 event per call caused the game to be
unbearably slow on Linux.  The old way was much faster.  I have solved too
fast a succession of mouse button down and up by not clearing the mouse flag
when the button goes up instead.

Fixed a memory leak and uninitialized variable after my refactoring of game
location changes; found by ValGrind.
