RC: Navring rework.

Better interface for users.
Get drawables from FW.

Added logic for tabletui and layouts (may need tweaking)

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.

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

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.

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

Cleanup a bit.
