Feature request: "Add to collection" function

[zeigerpuppy]

It would be really useful to have a function when accessing a grain to add it to a collection.
This would really facilitate work flow rather than having to go to the collection adding process to add a single grain.

I love collections by the way, a really great usability feature!

I agree. Currently Collections can only pull in grains through powerbox requests. It would be useful if it could also have grains pushed to it, through powerbox offers.
