Battery info update

[diogao13]

Hi folks,

At the control panel we find the battery percentage. It would be great an update to include more info, like a widget or simple click on battery percentage icon to present:

• current %
• last time it was recharged
• % when last recharged was initiated
• % when last recharged was ended
• a prediction when next recharge will be required, based on drain for a selectable period (3 days, week, month).
• draining graph using recharging date

I noted that Scubapro G3, already includes some battery management features.
