Title: Pytest compatibility

This pull request brings back compatibility with recent versions of pytest (anything >= 2.0 should work, but I haven't actually checked), cf. [issue 2542](http://code.google.com/p/sympy/issues/detail?id=2542). While this doesn't have all the customisations of our homegrown `bin/test`, it allows all the features of pytest to work.

To run all the tests, use `py.test -rXs sympy/`. All tests pass, except one failure for raises(), which has a different behaviour in `bin/test` and in `py.test`.
