Some improvements to continuous snapshot mode:

1) the interval between snapshots can be configured within the
'File Settings' dialog

2) the commandline option is now named 'ssinterval' instead of 'ssdelay'

3) the action is tied to the 'Alt/Cmd-s' key instead of a function key

There's just one more small issue to take care of in the Windows port,
and the next release should be ready.

   * Many changes to the FrameBuffer and UI code for 'smaller' systems.
     Stella will now scale correctly to small screens, down to 320x240
