VOL-25 - Add missing link to Enable Extension pop-up.
Add testing API Project
Make Project API testing class extend VolunteerTestAbstract to ensure that
CiviVolunteer is properly installed any time the database is repopulated.
Whitespace changes only (ran code formatter).
Separate API and BAO tests for Volunteer Project.
Eliminated unnecessary tearDown methods. If a method does nothing more than call its parent, there's no need to redeclare it.
Greatly simplified Project API test cases and code.
Refactored/cleaned-up Project BAO tests.
Renamed Project BAO testing class to better match BAO name.
