UI Changes 02/5/2014

- Login:
-  Now starts the main activity (with the user's wish list and friends
list) after a user logs in
- Removed the view (it was redundant and clunky-looking; the code
automatically brings up facebook's login if the user isn't logged in)

- Main Activity:
- Made a main activity to hold tabs for the user's wish list and friends
list
- Made fragments for the user's wish list and friends list

Logo:
- created logo and saved it in the appropriate dpis for different screen
resolutions
- added the logo to the app

TODO:
- flesh out fragments with the stuff Joon did
