Added 'Go to previous directory' event to the UI. Currently, this is

mapped to Backspace, and is used in the ROM launcher and various
BrowserWidgets.  The event can be remapped if desired.  When I'm
testing Stella, I tend to use the keyboard almost exclusively, and
it was getting a little tiring to reach for the mouse each time I
wanted to change directories.

Bumped version number.
