Creating a base node for an upgraded building does not create a node for the upgrade

[Crimsonum]

Buildings with upgrades require two nodes on the same cell: one for the parent building, and one for the upgrade. WAE currently has the same limitation as FinalSun/Alert where creating a node from an upgraded building only places a node for the parent building, not the upgrade.

It is debatable what behaviour is desirable here.

Could the behavior be:

1. Mapper places structure down with an upgrade (or two)
2. Mapper creates a base node
3. WAE checks if the building has an upgrade before creating a base node
4. If the building has an upgrade (or two) it will add the base node PLUS the upgrade(s) on the same cell.
5. When the base node is deleted, it will remove the base structure + its upgrades.

• Example:
  GAPOWR w/ 2 GAPOWRUP upgrades placed on map and are selected to be a base node
  WAE checks if the structure has upgrades. Confirms that it has 2 upgrades.
  WAE writes:
  000=GAPOWR,123,456
  001=GAPOWRUP,123,456 (same x,y pos as the base structure)
  002=GAPOWRUP,123,456 (same x,y pos as the base structure)
  When the base node is removed, WAE checks if there's a base node in the same position of the structure. If so, removes the structure + upgrades.
