Placing a mine will not destroy structures underneath, only hide them

[ldicker83]

Observed Behavior

When placing a miner bot on the surface on an untapped mine, the constructed mine shaft will not destroy the structure that's underneath. This leads to the structure underneath the mine still being in the StructureManager but not having any way to access or modify/monitor it yet any negative effects of it (e.g., collapsing due to neglect affecting morale) still apply and resources are still consumed.

Expected Behavior

Placing a miner bot on the surface will check below the mine and warn the user if there are structures underneath. If a structure is placed before the mine shaft is constructed, on the turn that the mine shaft is built, before this happens, the user is presented with the choice of either destroying the structure and allowing the mine to complete construction, or canceling the construction.
