Merge pull request #134 from acatinon/develop

Adding activated attribute for android.View.
Added javadoc for View.activated attribute.
Disabled test for ActivatedAttribute. View.activated property is not
supported by Robolectric 1.2. The test will be enabled once Robolectric
is upgraded.
checkedItemPosition, checkedItemPositions and choiceMode moved to AbsListView.
