MIME type regex too restrictive

[change500]

The transcoder does not accept uploads unless the mime-type starts with "video" - however, some browsers, such as Firefox, set the mime-type to "application" for m4v and mp4 files.

WPCOM VideoPress? uses exiftool to determine if the file is a video, this is no longer an issue. Fix will be in the next server release.
