Feature to add additional information on individual outputs.

I suppose this is partly solved by the merge of #6. What more is needed to close this?

I was thinking of having the same types of data as for the job attributes, so you can pass in bool,int,string and list, if anything is specific to one output.

Sounds good. I'm in the process of writing a couple of submit hooks for Nuke etc, and if I miss having the options I'll add it.
