Added pkg.flow.post() method to add/remove end-loop calls

Tank api method .post(), needed by the core package to calling parent fl
ows *from* a child flow. Thus far, events within the loop have been used
, but this was needed to avoid recursion. It's not the best approach, bu
t another would require making the tank aware of nested flows… trying to
 keep things simple!
The .post() method accepts a number or function. Th
e function is called when the flow stops - a number is returned as an id
 for the function added. When given a number, the function with this id
is removed from the post queue.
