3gp and mp4

These are very popular video formats for home-made videos so it would be good if gallery supports them.

I know, in next release, there will be movies from youtube support but i suppose it won't be very soon.
So, to that time movies (3gp) could be downloadable.

When i added 3gp format in main.php file, you can see that there is something but can't download it.


sorry, i didn't wanted to assign it to me :)
