clean up example app Dockerfiles/startscripts and put on github

[joel-bluedata]

It would be good to have them more easily available. Probably shouldn't stick them under the "deploy" directory... in fact maybe they should be in a separate repo outside of kubedirector (not sure about that).

As part of the process we should also give some attention to cleaning up the potentially confusing, vestigial, or just outright wrong bits left over from forklifting these examples out of the EPIC app catalog.

Related to issue #46.
