Revamped CustomLocale for the SDK.

- Revamped the list UI: replaced the long-press actions by some stateful buttons. Uses the listview's single choice mode. - Added a broadcast receiver to be able to change the system locale using an intent, e.g. sent by adb shell am. This is convenient for automated testing scripts. - Changed package namespace to v2. This makes it easier for an automated testing script to figure that an emulator has the old version and install the new one side-by-side. Change-Id: I1849d2b9d55441490b013cfefcca5d8fa48e22bd
