Suggestion: Enforce same-footprints for all upgrades of a given building

To allow for precise site planning, upgrade(s) should not have a different footprint than the original building (# of blocks wide x # of blocks long). Players shouldn't have to redesign their whole layout simply because they need to upgrade a single building. The level 1 footprint should be used as the base. Schematics exceeding this footprint could be handled in a number of ways:

• They could be considered invalid. An error would print on save, and the save cancels. This would be an ideal solution.
• They could simply be chopped off. This would be a lazy solution.

Totally agree the only schematics not responding to this are old ones and will receive a rescan soon
