Added windows build commands to build script

[HailStorm32]

Added "intelligence" to the build script to run different build commands if on Windows.

Also, given this uses the OSTYPE variable, the ability to run different commands for different OS's could be added in the future.

Correct, my only reason for moving the binaries was because they couldn't run in the Release directory. However, you bring up a valid point in that the way I went about it wasnt ideal.

My question then is this. Do you want me to remove the part the moves the binaries and just tell the user to do that manually, or move the movement of the binaries to cmake?

As it stands now, building on Windows requires the movement of files. It's not just the dlls that its missing, but also the log folder and .ini files. Hence why I moved only the binaries, as it was less to move. I presume the rework of the build system will take this into account?

Yes the fixing of the build system to actually work on native windows will be fixed in #670 .

@EmosewaMC removed OS check and switched to cmake
