UserfilesController actions as portal side tasks.

[natacha-beck]

I'm not sure if this idea makes sense, but hadn't we discussed at some point having quick tasks run without communicating with a bourreau? I remember this coming up for the whole "make new file collection from subsets of other file collections" idea. If that idea is still on the table, I'm gonna suggest that a whole heap of UserfilesController code should be handled in this way. All the compression, file collection creation, and perhaps even most of the create action should be handled by these kind of tasks. Thoughts?
