Added a ProgressDialog class, which shows a sliderwidget that represents the

progress of some activity.

Some additions to the LauncherDialog.  When populating the ROM list by
directly examining the ROM files, it now uses a ProgressDialog to show
the current status (since this operation sometimes take a long time).

The last selected ROM is now re-selected when starting Stella.

Some minor code refactoring to take into account zipped ROM support
(yes, its coming soon).

Re-added paddle support.  Still TODO is tweak the sensitivity of mouse
movements.  Also still TODO is re-add joystick support.
