Add ability to remap softkeys HTC One M8 4.4.4

[Former user]

Please add the ability to remap the Recents/Menu button to either recents or menu.

With 4.4.2, I was able to modify this myself in the vendor settings database, but this database isn't used in 4.4.4.

Thank you!

Sorry, I don't have M8 and don't have soft keys on M7, maybe some day)
