Lp preceptors and Course End Evaluations

Adding LP Preceptors Evaluation as well as the Course End Evaluation.

:x: Removed  app/controllers/my_evaluations_controller.rb  as it wasn't being used anymore.

:mailbox: Adding mailers for both the LP Preceptors and Course End Evaluation alike. Both Development and Testing environment emails get sent to me but the productions emails get sent to both you and Linda.
