Freeze modules to save energy

[keineAhnung123]

Hello,
It would be cool to freeze modules to stop them from updating etc.
This would reduce CPU and so on.

For example a PIR sensor turns off the screen and freezes all modules.
And if the screen gets reactivated the modules will unfreeze.

What would you think?

@keineahnung123 that is what they do now. sent suspend(). should do nothing til resume()
