Import SDL 1.2.14 and GLEW 1.5.4.

I am not replacing the following header files used by the Windows build,
as I don't have a Windows build setup to test. Please point the Windows
build at the header files inside these clean distribution packages and
garbage collect the duplicates: GLew/*.h and SDL/Include_1.2.
