Suporting Hybrid-Sleep

[BillyCroan]

Hybrid Sleep is a combination of hibernate and suspend. The system prepares to hibernate and writes memory to its swap file, then it suspends. If power is lost, then the system can boot and restore memory from disk. If no power loss and the user presses the power button to resume then it simply comes back immediately.

I want to support Hybrid Sleep with your extension:
I tried changing

this._systemActions.activateSuspend();

to

this._systemActions.activateHybridSleep();
and of course its not that simple.

Where can I see the library of functions supported by _systemActions?
