Renamed SIL.Media to SIL.Windows.Forms.Media

I wonder if it might be best to split SIL.Media into a utility DLL and a Forms DLL, as we have with the other things. There are only a small handful of WinForms-specific things here.

If it's a small handful, would there be any value in absorbing it into an existing library? Is the benefit of a separate dll enough to justify its cost?

I don't see any logical fit anywhere else. The only possible place would be Core, but everything uses thats, so I think it would be less than ideal to put it there. Eventually, HearThis will probably become a non-WinForms app (or get a non-WinForms cousin), so breaking the functionality up really does make sense. I don't know enough about the architecture of Bloom, but it would be another possible candidate for using stuff in SIL.Media if it were not WinFoms dependent.

I'm also fine leaving it as is. The only thing this PR does is make the name less misleading.
