added functions to allow for cwise min/max operations with scalar argument (bug #400).

Browse Source 
added function for array.min(), array.max(), matrix.cwiseMin(), matrix.cwiseMax().

The matrix.cwiseMin/Max functions required the definition of the ConstantReturnType typedef.
However, it wasn't defined until after MatrixCwiseBinaryOps was included in Eigen/src/SparseCore/SparseMatrixBase.h,
so I moved those includes after the definition of the typedefs.

tests for both the regular and scalar min/max functions were added as well
