Refactored program feature model;
  - renamed Entry to Presentation

started implementing changes to Program Feature on client side
Merge branch 'envived-aiwo' into f/schedule_browsing

Conflicts:
	EnvSocialApp/src/com/envsocial/android/features/program/ProgramFeature.java
- refactored program schedule view. Work still needs to be done to show the presentations by session.
- implemented browse locations (areas) feature for an environment. This feature automatically gets added to the DetailsActivity grid
  view if the current location is an environment.
- implemented featured CheckIns and History of Checkins in the HomeActivity
- refactored the way in which an Anonymous User is created; there is now a separate call to the server to accomplish this, as opposed to bundling
  the functionality with the checkin action; this makes for a clearer separation of the result of each server action
- almost ready implementation of BoothDescriptions
