Show different glowpad options for incoming video call.

- Refactor code be more flexibile/specific in specifying the targets
for the glow pad; went from "n-way" labeling of different target sets
to more explicit labeling of scenarios, such as "audio without sms".
- Add target sets and cases for showing targest in AnswerFragment.
- Added new drawable for the target to answer a video call.
- Add method to GlowPadView to allow changing the handle (now it may
be either a videocamera or phone icon, depending on the scenario).
- Add a new video handle for incoming video calls.
- TODO: Hook this up to show these glowpads if there is an incoming
video call.
- Deleted some unused resource files.
