Added three buttons to action bar, Search, Login, and Favorites
Login is a dark button used as a test
Search provides a text field
Favorites is a star taken from android icons and edited in paint
A switch statement was added to mainactivity.java to handle future implementations of the
buttons.
Need to add a MapFragment, depending on which map library we choose.
Added new images for the buttons and main_activity_actions.xml
main_activity_actions.xml contains the definitions for items in the action bar
Added the files from bikeshare/res which I accidentally omitted last time.  Also added .jar and R.txt files
that I left out last time.
Stars without white backgrounds

removed the white backgrounds from the stars
Added launcher icon and map
Added libraries needed for map
Fixed map zoom and center
Merge pull request #2 from bikeshare/working
