Title: 694 wester tests

In response to asmeurer's request in Issue #694 that we get the most recent as-of-now-floating-in-others'-repos test_wester.py and commit them, I've merged effect's most recent changes into asmeurer's. This now provides a history of the file. In addition, I've added my own bug fixes to the tests and added @XFAILS to tests that just wouldn't pass for me, along with some cryptic #comments in-code as to why.

Pulling into sympy/sympy will make improving the tester wests, I mean wester tests, a bit easier.
