Changed connect dialog...

Instead of displaying "Update Firmware" button, displays "info" button which
displays a dialog with all sorts of robot info.
Got rid of old button handlers
Updated libbarobo to use latest version
Updated firmware hex file
Merge branch 'async_framing'

Conflicts:
	connectDialog.cpp
Updated version to 1.5.5
Merge branch 'master' of github.com:Barobo/RoboMancer
