Touches nearly everything unfortunately but is necessary.

Move MatrixProperty to Kernel, there's no sense it being in API now. Also expose Matrix types to IPropertyManager. We may have to figure out a better design for the TypedValue situation but for now we're good. Refs #3175

Refs #3175. Sorry for the huge commit but certain things require Matrix to be in Kernel. Given how Quat, V3D and Matrix inter cooperate it seemed sensible for them to be in the same place and arguably this is where they belong anyway.

Refs #3175. Move the macro for defining IPropertyManager::getValue functions to the header so that all user-defined types can access it. Also implement a test for MatrixProperties being passed to algorithms. We have one problem now with this kind of code: DblMatrix R = getProperty("R"). IPropertyManager can't define a template conversion operator because Visual Studio has a problem with the std::string version that even a specialization doesn't cure.

Refs #3175. Add a MatrixProperty that will allow Geometry::Matrix objects to be passed into algorithms. Also renamed the MantidMat typedef to DblMatrix so that it's clearer what the thing actually is.
