Naming scheme of videos has changed

[vik]

I plumi 0.2.3, the URL scheme of a video is:

 http://site/Members/member/videos/video_filename.mp4 - downloads original

 http://site/Members/member/videos/video_filename.mp4/view - views in the embedded player

In plumi 3, the scheme is:

 http://site/Members/member/videos/VideoTitle - views in embedded player

 http://site/Members/member/videos/VideoTitle/download/video_filename.mp4 - downloads original

The difference is in the new system, the URL is calculated from the title, which in the old system, from the filename. For migrated videos the following will occur:

 http://site/Members/member/videos/video_filename.mp4 - views in the embedded player

 http://site/Members/member/videos/video_filename.mp4/view - views in the embedded player

 http://site/Members/member/videos/video_filename.mp4/download/video_filename.mp4

This may break some links (namely to the original files), and cause other wierdness/inconsistencies if the old and new systems are combined
