Support for video/mp4, video/ogg, video/webm

Added support for the three leading HTML5 Video mime types
.mp4 video/mp4
.ogv video/ogg
.webm video/webm

When Internet Explorer 10 or 11 receives application/octet-stream as the mime type for HTML5 video, it will not play the video. This resolves the issue in an Apache/mod_mono environment.

Update: 2014-01-30

I've since added numerous mime types that will allow HTML5 applications to function properly.

1. The addition of the common audio/video media types allows mod-mono to correctly deliver the files, as some browsers reject the content if delivered as application/octet-stream.

2. The addition of common Microsoft office document mime types will allow browsers to open them properly when the office plugins are installed.

3. Added support for .xhtml, .dtd, .rss, .atom, and .json files

4. Added support for HTML5's Application Cache by supporting the .appcache extension. The server must deliver the content type as text/cache-manifest for it to work.

5. Added support for TypeScript, CoffeScript, and DART script files.

6. Added support for common HTML5 3D modeling files.
