Development Settings: fix setting reset on disable

When Development Settings are disabled, some settings are
reset to values other than the default. This fixes it.

 - No need to have resetAdvancedReboot(), as it is already
   reset by the "unckeck all checkboxes" logic.

 - Adb notify should reset to enabled

 - Verify apps over usb should reset to enabled

Colour picker text input field: wrong content due to alpha channel.

The field was, effectively, showing AARRGG instead of RRGGBB due to
the alpha component being non-zero. This change fixes that in a
generic way which allows for alpha channel handling even though I see
no use for the alpha channel for the notification light.
