Removing deprecated Restorer and ezRestore references

- Not recommended to be used in new designs
- Just pollutes warning messages during compilation (hiding ones that
should be fixed)
- Updated test code to use bootstrap
- Sped up some of the test code that was just sleeping while waiting for
the server (now polling for the socket)
