Using noun instead of verb for inverse matrix function.

Mainly to be consistent with Matrix::transposed() function name,
furthermore calling

    Matrix::inverse()

could look like the original matrix is being inversed, while calling

    Matrix::inversed()

implies that the function doesn't change the original matrix, but
returns the result instead.
