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.
