Support getting session data for all worker threads when more than one is used about sockethub

session data, yes, but not objects which have state-full connections like xmpp, imap, pop or something

hmm. im not sure what i was talking about when I made this bug :) should have been more descriptive.... postponing...

I think this means that if there are several listeners for the facebook platform, make sure that each of these instances can fetch the encrypted session data and handle events independantly from each other without one listener getting a job, the second one getting another job from the same session and being unable to operate without context.

does not apply to new code format
