Conditionally ignore key repeat

For the following actions:

 * reset scaling ('s'),
 * redraw ('r'),
 * scale to actual size ('a'),
 * center image ('c'),
 * remove selection ('x'),
 * toggle fullscreen ('f'),
 * toggle playing (space),
 * print selection ('p'),
 * toggle overlay ('d')

repeating action when key is held does not make sense.  After acting upon these
events ignore them until key is released or another key is pressed.
