coordination: add option to jump into state-machines

by passing the argument :starting_state the user can choose
states in which a statemachine should start.

These states needs to be dinfed within the statemachine as:

prepare_jumpin("wall" => wall1, "pipeline"=> pipeline1)
Ah ... Missed this one. This method is wrong, it is looking for a state, not a task, so (1) has nothing to do in Base and (2) is badly named. You should modify it to test only against name.to_s (not #{name}_state} and implement a find_state_by_name in ActionStateMachine that calls it with #{name}_state.
