[TIMOB-23149] Android: Add editing support to ListView

We have editing support on ListViews for iOS and we should add parity support for Android. On Android you longpress items to select/deselect. The List Item image mostly changes so show the selection, although this seems to differ per app. The ActionBar title shows the number of selected items and the actions appear in the ActionBar menu. See the attached movie for examples of Google Hangouts and Gmail. The [Material Design Specs](http://www.google.com/design/spec/components/lists.html) for Lists do not include actions.
