new atari 800dc update

[pavelbure]

chris emailed me with a update of the atari 800 emulator.

The changes from 0.76 are

* enable basic R: device emulation with the DC Coder's Cable (no
modem controls; fixed to 8n1; baud rates 300 - 9600)
* use Atari800 2.0.3 code base
* use KOS svn code base version 560
* add possibility to switch X and Y axes of controller input
* ability to disable either the D-Pad or the Joystick of the
controllers (in "Controller Configuration" menu)
* ability to disable or enable Bienias' sound improvements. They
are too heavy for the DC and therefore disabled by default. 0.75
had them disabled, 0.76 had them enabled, now it's selectable.
* when saving or restoring state display a "please wait" since
accessing the VMU is very slow. This was already in 0.75 but got
lost in 0.76.
