Neutron Refactoring

v2_0 -> v2
No options (redesign)
More features (extension-related)
Some bugfixes
The new live tests pretty much are a 1:1 rewrite of the old neutron tests. Unfortunately, they might need to be refactored more to use proper setup/teardown - in some cases, especially failures, you will have left-over entities. Running this test is a nice way to cleanup your account, but doesn't make sense leaving it enabled. It might make sense to control it through some sort of property instead of just commenting it out, though. Best solution would be to refactor the tests though.
Thoughts?
