Document Module Assemly Component

[Xiphoseer]

For the module assembly component, if it exists, use the rebuild componentID to lookup the info for the lot that has a module assembly component in the Modular Build Component table. This is how you are supposed to know what lot to give the player if they complete a build in a specific module assembly build area. Doesnt seem to be documented anywhere and its hard coded in dlu so thought id mention it
