Fix spelling of PPRTestIntialiser class.  Remove PPRTestIntialiser.h and replace with PPRTestInitialiser.h.  Similarly with PPRTestInitialiser.m.

PPRSettingsViewController.m:
- replace use of PPRTestIntialiser with PPRTestInitialiser - import of header, use of class.

PPRAppDelegate:  similarly import of header and use of class.  Ditto PPRSchedulerTest, PPRClientManagerTest, PPRFacilityManagerTest, PPRActionManagerTests, and PPRActionSchedulerTests.
in project.pbxproj, add PPRShift.m to two lists.
Update PPRTestInitialsier comments to reflect who created and renamed the files.
