RC: Navring rework.

PS1: Better interface for users.
     Get drawables from FW.

PS2: Added logic for tabletui and layouts (may need tweaking)

PS3: Cleaned up strings
     Added long and short discriptions to the pop up dialogs
     Since long press action have no icon I made a friend uri toast
     message to let user know a long press action was set.

PS4: simpify the dialogs a bit. still need to fix custom icons...

PS5: Fixed custom Icons did more dialog work.
     only 2 things left. tabletui/landscape layouts need tweaking
     need to move target selection and enable longpress inside the new
     ui. Getting close this is pretty functional.

PS6: Adjusted custom icons size.
     Moved Enable long press and amount inside the ui
     moved Navigation ring to its own header in main activity

PS7: Cleanup a bit.
     fixed crashing on changing target values
     Now using a spinner and switch for target number and longpress

     Switched to enum and switch case for dialog functions

PS10; rebase off new awesome action. clean up things Jon pointed out
