Ability to disable automatic placement helpers on Lasers, Bridges, and Funnels.

[Aneonen]

Description of the feature

An Item Properties option (or suitable alternate) that would allow designers to disable automatic placement helpers on Lasers, Bridges, and Funnels such that they cannot fight with custom ones.

Why should this be implemented

For most users, the automatic placement helpers that generate at the terminus of these entities are useful, but those who use the portal magnet item for a more controlled experience may find that the automatic magnet will fight with their own.

This is most evident with vertical funnels; if a funnel projects onto a restricted surface, the automatic magnet will invalidate a user-placed one and prevent the player from properly placing a portal upon the desired surface unless the player is standing in specific, uncomfortable positions, or manages to shoot a region contained in only one magnet. It is not always reasonable to expand the surface the funnel projects onto and allow freer portal placement.

Though less relevant for lasers and bridges, it is still noticeable, and the consequences can range from lightly frustrating players to allowing portal-positioning exploits that players might not even realize they're exploiting while playing.

Additional information

This is partially redundant with the very old #1114, though I think the idea is still relevant. The automatic placement helpers should certainly be enabled by default as they still benefit most players. This option would be potentially slightly more destructive for inexperienced players than most of the other StyleVars/Item Properties options, but some other settings can be abused already anyway.
