Major Fixes

Major fixes to the ImagePacketSender as well as the ScreenCaptureDriver.
The ClientCapturer is still not ACTUALLY creating any images, but that's
an implementation detail. The rest of it seems fairly sound.

Still need to work on the "Connect" function, but that should sort
itself out.

Next step is to work on the server, then the visualization. Perhaps I
can get John to help out on the screen capturing side of things.
