Add option to hide media items in tag search

[thegoldmolar]

I know that the "show galleries" box isn't supposed to hide media items, but I wish there was an option next to it (or just included in that box) that also hides media items.

I would much prefer if searching resources by tags was as easy as just clicking the tag, then clicking a box to ONLY show resources. When I click on a tag, it's because I want to see all the other resources that share it, nothing else. I could be in the minority on this tho
