General propose bluetooth remote control

The idea is to create a general propose bluetooth remote control for Elphel 353 camera.

USB-bluetooth should be used as a com-port and we can run a console with a shell on it. On the other end we need to write some JAVA software for mobile phones to control the camera. This software should come with an editable template. When you press a key on your mobile phone it execute a shell command or a script on the camera.
