Room77: Battery -> Please put back into cradle

[rootzoll]

It can happen that bar tender forgets to put the POS back into cradle after use. The device should monitor Battery and maybe starts to beep (maybe with screen info) to remind user to be put back into cradle so that it stays operational for next action.

Can confirm this also happens. Alternative solution (loud bar might not hear beeping) is to make screen show Low Battery Icon when it is low.
