Added serial number to UI.
Removed support for API level 10 (Gingerbread/Android 2.3) as it is
currently not needed.
Following changes were made to facilitate the change:

-Replaced all support library calls with framework equivalents
-Removed lint checks
-Replaced deprecated Clipboard calls
-Reverted back to IOIOActivity in IOIOLib as custom IOIOFragmentActivity
