Move InformationDevices functionalty to static functions

[tunbridgep]

Currently, the mod creates "InformationDevices" for each object - datacubes, etc.

However, other mods (GMDX AE) do things to the DataCube class directly.

This sort of "multiple-inheritance" should be possible by inheriting DataCube (using a DXRDataCube class??) and calling the static functions.
