Support Cesium tiles with the interaction toolbox

Added:

• SUpport for using the measurement toolbox tools on cesium tiles
• Marker, distance, plane was already supported out of the box (if cesium tiles have collision
• Clipping box needed to be adapted using cesium raster overlay polygons (see this thread: https://community.cesium.com/t/remove-clipping-cesiumpolygonrasteroverlay-added-during-runtime/32520)

Fixes:

• Fixed 3D menu not staying exactly in front of player pawn when moving
• Fixed laser pointer in ARENA2 appearing to have an end point sphere in the middle. Cause was that the pointer was spawned twice through a then 1 then 2 sequence in ParentPawn
• Scale location markers and their labels for a longer distance when moving away. Necessary for Kolumbo or other models when resolution is not high enough to stay close to the model

Closes #23 (closed)
