Choose excursion avatar from image pool

TBD: should Avatars_for_rails target ActivityObject rather than Actor in Social Stream? What are the technical challenges in refactoring this? Are we willing to do it?

If so, this bug maybe pertains more to Social Stream than ViSH; otherwise we can modify Avatars or just re-implement and avoid reusing it altogether (which would be a pity).

It seems like we won't be using Avatars_for_rails after all.

I commited some code to let each excursion have a thumbnail from the pool (thanks @diegocarrera for the really nice pics), but we should write a view and maybe patch the excursion controller to let users choose. OTOH there's no way to choose an excursion title or description yet, so don't hold your breath.

Acording to @ntoribio this will be integrated in the vish_editor, along with title and description

[rafaelgg]

We just assigned a random thumbnail to each excursion in our production system. These may be changed when we acquire this functionality.

vish_editor team to take care of this.

This is working since ff18421. Closing.
