JavaGear Android Port



I've started to port JavaGear to Google's Android platform. The results are good, although it runs seriously slowly in the emulator. Based on the J2ME version, it will presumably run faster on an actual device.

There will be updates to the existing mobile version of JavaGear in due course. I'm hoping to add Lightgun support for touchscreen handsets.

There's still some debugging on the Android version to be done in the meantime, and I've got to merge the Android code into the main source tree, as it's forked at the moment.
