Bundle all feed videos for each update

Adds a new configuration option that tells glass
to bundle all videos from a feed together and
post it whenever a new video is posted.
Switch to Alarms

- Switches the updater to use alarms
instead of a thread that sleeps. This should
ensure the service continues to work even
while Glass is sleeping
- Fixes a bug where the last video id
was not being properly used when
sendAllVideos=true.
Fixed a bug where the service could not be launched
Dont start sticky

Starting sticky is not what we want to be
doing since we moved to an Alarm-based
system.
