Change math constants, similar to PR #372. Use M_ namespace with the de facto standard M_PI and its ilk. Change names that are widely used in the project to be in the M_ namespace, so HALFPI becomes M_HALFPI. HALFPI is #defined as M_PI_2 (the defacto standard name). #defines _USE_MATH_DEFINES for MS Visual Studio (I didn't personally test this part, but Appveyor will not build otherwise).
