Request: Prototype/AutoplaceControl mandatory property

[ShadowGlass]

Please add a new property for the 'autoplace-control' prototype:

mandatory

type: bool
default: false

If true it disables (or removes, whichever you prefer) the checkbox on the left of the autoplace control, so the player can't completely remove the resource or terrain feature from map gen.

Hey, this was added in 1.1.54 as AutoplaceContro::can_be_disabled.
