Change some elements to use Factum Solus models in Portal 1 style

[bitgen-was-taken]

Description of the feature

In the Portal 1 mod "Factum Solus", there are Portal 1-styled excursion funnels and lasers, and I think they should be used in the Portal 1 style in BEEmod.

Why should this be implemented

They look more "Portal 1-styled" than the currently existing ones.

Also, this mod adds a (imho) very nice-looking player sensor.
