Title: Migrate certain unit variables to passVars in new chains

Certain chains need to be able to inherit passVars set in previous chains. An example of this is identification, where a second pass of identification happens after extraction during the transfer; the previous choice made needs to be able to apply.

Unit variables with the variable name `replacementDict` will now have their values included into passVars at the creation of every subsequent chain in the unit.
