HTTP served tests, multiple server support, real logger
added travis file
integrated sam's feedback

- bumped to version 0.3.0
- added 0.3.0 migration steps to the readme since I broke backward compatibility, again.
- passing client name in the options is better than get/set and consistent with the rest of turtle
- better file serving. Now only test files can be accessed and are scoped per client.
