Integrate support for MinGW Win32 builds.

* Add Win32Depends.cmake, which retrieves all dependencies from
  the Internet. Other ways of building the application on Win32
  are not supported.
* Install the application correctly on Win32.
* Make FindGTK2.cmake search for GIO.
* Make the project a C-only project, so g++ is not needed.
* Remove obsolete checks for strtok().
* Set WIN32_EXECUTABLE on the application.
