Massive amount of work to improve the test suite, restores doctests. After Brian's comments, I realized that our test machinery was NOT in reality running all the ipython-syntax doctests we have. This is now fixed. The test suite isn't completely passing, but this commit is for the underlying machinery. I will now work on fixing as many broken tests as I can. Fixes https://bugs.launchpad.net/ipython/+bug/505071
