usb: Add ability to prompt user about what to do upon usb insertion

 v3: Add in config option
 v4: Bugfixes
 v5: Force a redraw upon exiting
 v6: keypress-in-chargeonly mode enables mass storage (and vice versa)
 v7: Fix bootloader builds
 v8: Update manual, and have bootloader respect keypresses
 v9: Change default to mass storage (ie no change in behavior)

 todo:
  * test-build dx50/dx90
  * Switch from yes/no to proper menu?
  * prevent WPS progress bar from drawing over us
