Implemented multiselect in NUI for VisualVoicemailFragment.

This solution has a couple hacks in it because the DialtactsActivity has a
non-support ActionBar and MainActivity has a support Toolbar. When multiselect
is implemented for NewVoicemailFragment, we should be careful to use support
action mode instead of non-support action mode so that the transitions and
styling are seamless and consistent.
