[SciPy-Dev] Two speed/enhancement PRs

[Jacob VanderPlas]

Hello,
I currently have two small open PRs which are basically ready for merge, 
and have been sitting inactive for a while.  I'd love a few people to 
read-through so we can merge:

https://github.com/scipy/scipy/pull/289
This PR speeds up the pseudoinverse calculation, adds a fast hermitian 
pseudoinverse, and adds a `return_rank` option on all pseudoinverse methods

https://github.com/scipy/scipy/pull/311
This PR speeds up single-row access in CSR matrices, and allows for fast 
generic slicing of CSR matrix rows.

Thanks!
    Jake
