Title: TIMOB-4482 Android: For TabGroup, put tabHost in a TiCompositeLayout so as to support position animation beyond screen size

http://jira.appcelerator.org/browse/TIMOB-4482

test case is the fail case app.js in the JIRA item. When you tap the button the TabGroup should animate up/down (except for the very first time you tap the button, which doesn't do anything because of the way the test is written.)
