Non-JPA implementation, added more complete service infrastructure.
Non-JPA implementation, added more complete service infrastructure.

- Removed JPA from domain model classes and removed
  repositories to avoid problems encountered with some of
  their magic. Revisit later.
- Added tests and addressed (most of) issues around tests
and profile settings that I was seeing (tests fail in IDE,
but pass in command-line build).
- Fixed Gradle Wrapper
- Added Service interfaces for Ads, Bids, and History and
  provided implementations for each. The BidServiceImpl is
  currently returning fake data.
- Updated comments about project.
