Updated all repositories

I think the master branch of all repositories are now working together.  I tried cloning and installing fresh from this commit --  

pyclaw passes all the nosetests and examples in amrclaw and geoclaw run and plot properly and the tests in amrclaw/tests pass.

Someone else should check this before merging.

Then I want to check if travis is working in the amrclaw repository, where it should check the tests in amrclaw/tests.  If so I have tests to add to classic and geoclaw.
