Add anchor to scene path, and display stream anchor

This allows to play videos which are not supported by JWplayer. Stash will display links to the local file and the stream in the "File Info" panel. This allows to open the stream or local file directly in the browser (if supported) or the app that is registered for the respective file type (e.g. VLC).

This addresses issues #52 and #62 (which are basically duplicates)

I think that the plan is to have the server side use FFMPEG to do live transcoding for that kind of stream at some point but this might be nice in general so long as it's got a CLI flag like --verbose was just PR'd recently. I know that this thing isn't designed to host content on the internet but being able to switch on and off additional features would be nice.

Imho the specific feature could be a an extra tick option in the interface configuration (like Display titles and tags) at least for the short term untill live transcoding is possible.CLI options are convenient but mainly for the backend.

The local file link is only valid if stash is running on your local machine obviously but the the stream link works fine :-) and is indeed very useful for wmv , hevc etc media files.
