Allow templates to snap (to resources)

[Garanas]

Description

When you try to build an extractor or a hydrocarbon plant your build preview will snap to the resource deposit. This radius of behavior can be changed via the console commandui_ExtractSnapTolerance .

When you enable a template preview via SetActiveBuildTemplate the snap behavior is disabled, even though the build mode is still set to an extractor or a hydrocarbon plant.

Suggested change

Do not disable the snap behavior. The snap behavior should still apply using the context of the unit that you entered build mode for, unrelated to the units in the template.

What we can do with it

This would allow us to extend the Context based templates feature. By allowing snapping to work with build templates it will be easier to place down templates that include extractors, storages and even fabricators.
