Enable galaxy logging during Selenium tests.

- Use localStorage to enable the logs at the start of new connections during tests.
- Add new flatten console logging options in the client to hack around problem recovering multiple argument style logging the client uses with only getting back first argument when using Selenium API (at least with Chrome).
- Break out the browser log into a sort of default and verbose mode (only the latter includes DEBUG and INFO messages).
- Use json.dump with the indent call to get more visually parsable logging messages in the Selenium test failure dump.
