Add a collection option to 'addmedia' command line uploading functionnality. Specify the collection with its slug.

Use like this:

gmg addmedia user file.jpg -c collection-slug

​Here's the patch

This is my first contribution, please tell me what I did wrong :-)

On each upload via web interface I have to select the license per media. I have strong default preferences and would like to set my default preference in my profile settings. This one would be pre-selected when uploading via web.

Apps uploading via the API will likely select their own license or could then use the user default license if they don't specify one.

Currently account creation is an all or nothing. If you allow to create accounts, people can upload stuff. I want to limit uploading to a selected circle of priviledged ones (lets call them family) and let other comment on the nice cat pictures we upload (let them call friends). Currently that is not possible. They can not comment as account creation is prohibited, as server space is limited.

You get the point. :). Until commenting via OpenID is implemented, I'd love to enable account creation, but not uploading. essentially that boils down to 3 user levels (commenter, uploader, admin), I guess. Do I make sense? P.S. I don't have a cat, but kids which boils down to the same problem, just with less hair on the floor.
