search.go: create download links for unwrapped MTS media in quick search results

Issue #317 resolved
Trek Hopton created an issue

The quick search feature on VidGrind’s search will be made the default (see issue #316), but currently the only link provided will download MTS wrapped media (.ts). Users will likely want to download media without MTS (eg. PCM or h264) so we should provide this link.

We want to avoid serving media for all the results so the click of a media download link should trigger a get request for the media. The request query should be similar to the existing download link (see t/search.html line 297) but contain out=media (see line 547 of video.go)
