Add documentation referencing other implementation.
CB-4404: Changing where android:windowSoftInputMode is in the manifest so it works
CB-5971: This would have been a good first bug, too bad
Delete explicit activity.finish() in back button handling. No change in behaviour.

The default handling calls through to Activity.onBackPressed(), which
by default results in activity.finish(), but can be customized by the
app.
Merge branch 'master' into 4.0.x (back button default behaviour fix)
