Long-long press for mapped buttons

Reimplementation of long-long press (long press for buttons mapped to long press).
There has been several pull requests already, some has been merged (or the same conclusions done), so the difference is smaller over time.

Note commit: 
 	5a080d2: https://github.com/gerhardol/xposed-additions/commit/5a080d288a383bdf17807e3265bf79a66f25d99d
Seem to be an issue for non-Pro also in 3.4.0

This first part has few actual, changes, but is preparing for other changes.
If they are not accepted, it may be possible to complete the patch anyway.

Changes so far:
 * Long power press handling (discussed in the 3.3 pull request)
 *  	5a080d2 (Non-Pro action handling in 3.4)
