Issue #65: Video don't play with FireFox. Don't change media when it's not a photo.

Solves issue #65 (closed).
Tested with FireFox and Chromium. One of the reasons why it's more visible on FireFox is that you can start a video when you click on the player image, while on Chromium you have to use the play button in the control bar. Probably could be a bit nicer by changing the mouse icon when over the HTML5 player, but at least it works correctly.
