Binaries for MacOSX and Windows 10 64 bit

These are portable binaries for MacOSX and Windows 64 bit. They are produced using Qt version 5.10.1 and either clang or Visual Studio 2015. They have been tested under Windows 10 and MacOSX 10.13. The binaries should also work on recent 64 bit versions of MacOSX and Windows but have not been tested on earlier versions. The source code should compile on Linux but I would expect there to be a few edits necessary depending on the Linux distribution used. There should be very few external dependencies since most (if not all) of the required files are packaged in the source code distribution. The source code could almost certainly be compiled for 32 bit systems too but again there might need to be some editing.
