Title: Added Lyapunov, Algebraic Riccati Equation Solvers with Tests.

I've implemented matrix equation solvers for the following equations:

* discrete and continuous Lyapunov equations
* discrete and continuous algebraic Riccati equations

These solvers live in scipy.linalg in a new file "solvers.py." I've moved the recently added Sylvester equation solver into this file as well. The module docs now have an additional subsection "Matrix Equation Solvers" to differentiate the matrix equation solvers from the solvers in the Basic subsection.
