run_callbacks

Runs the callbacks for the given event.

Calls the before and around callbacks in the order they were set, yields the block (if given one), and then runs the after callbacks in reverse order.

If the callback chain was halted, returns false. Otherwise returns the result of the block, nil if no callbacks have been set, or true if callbacks have been set but no block is given.
