Did a HUGE amount of testing with the amazing help of @domenic as part of #41, and we finally got the right configuration sorted out! This update is a reflection of the changes required.
As we now only copy across some of the GDI display settings, we aren't able to have really tight matching on the GDI part of the Windows display profiles. For this reason, I loosened off the Equals test so that it would match on the functions that we change within DisplayMagician. The profile matching now works correctly.
