oppo-common: enable permanent menu key

tbh they have hw keys...yes...but the screens are far to big and google
will add the menu button in apps as permanent feature in future release.
So enable it by default....now kufikugel is happy :p

oppo-common: add DeviceHandler package

this apk just keeps the handler which peforms the gestures and double tap
when screen is off.

We will extend it on a later point with settings....but we will use instead CM settingsour DSLV
which will allow to add any action the user want (#link:SlimActions).
