Moving extensions to either quarantine or deathrow....

Moving extensions to either quarantine or deathrow. When a module is moved to quarantine, it means that while we intend to keep it, it is currently broken or sufficiently untested that it can't be in the main IPython codebase. To be moved back into the main IPython codebase a module must: 1. Work fully. 2. Have a test suite. 3. Be a proper IPython extension and tie into the official APIs. 3. Have members of the IPython dev team who are willing to maintain it. When a module is moved to deathrow, it means that the code is either broken and not worth repairing, deprecated, replaced by newer functionality, or code that should be developed and maintained by a third party.
