Allow option to disable production during factory buildup

[deathreaperz]

Description

As per title. In vanilla, during factory buildup, we can produce the techno.
Realistically, it can't until the buildup finishes. It will also not sync with features such as custom BuildupTime.
This feature can solve the problem above.

INI code

[General]
DisableProductionDuringBuildup=false ;boolean

[STRUCTURE]
Factory=BuildingType/InfantryType/AircraftType/UnitType
DisableProductionDuringBuildup= ;defaults to [General]->DisableProductionDuringBuildup
