New issue 2515 by nicolas....@gmail.com: trigsimp fails to simplify x*cos(x)*tan(x)
http://code.google.com/p/sympy/issues/detail?id=2515

When working on solver(), I noticed that trigsimp() fails to simplify() some trivial expressions, like x*cos(x)*tan(x), or sin(x)-cos(x)*tan(x).

I've made a patch, and test_simplify() tests pass now.

I'm running full test right now.

I'll make a pull request soon (but I want to know the issue number before doing so).
