Add Windows application manifest

- Use common controls 6 so error dialogs use correct visuals on
Windows XP or later!
- Specify running as invoker so Windows doesn't guess if it should
prompt for admin permission on Vista or later.
- Specify compatible with Vista through Windows 10. Tells Windows
not to emulate Vista behavior, not sure if it affects anything.

Makefile automatically runs windres when manifest changes.
