Support preview rendering

[Scott Gifford]

MovieMacro should be a preview renderer for movie types. That makes it show up whenever a recognized video file is shown, without the user having to download the file or embed it with MovieMacro.

I will attach a patch that implements this.

Patch to support preview rendering

Replying to sgifford:

The two cases I think that of where this would apply are the attachment page and the browser. The next checkin will add support for both. Please let me know if you can think of any others.

(In [12037]) Refs #8808:

• Added preview rendering of movies. Previews are rendered for attachments and repository files. For preview rendering to be available for all attachments, set the value of the [mimeviewer] max_preview_size configuration entry to greater than or equal to the value of the [attachment] max_size configuration entry in trac.ini.

The initial version of the patch was by sgifford. Thanks!

[Ryan J Ollos]

Feedback from testing is appreciated. You'll need to enable the new movie.web_ui component in trac.ini, or through the web admin panel.

I was having a strange problem with the pages needing numerous refreshes initially, before the IHTMLPreviewRenderer first seemed to register. I think this was probably just an issue with my development environment, but please let me know if you encounter any similar issues.
