support to include chunks from default preset in external presets

[skyper]

I did try to import the chunk for surface=* in an external preset but it does not work.

Would be nice to use chunks from default preset and also to be able to link to one of its items.

preset_link between presets from different source does work but adding an additional link to defaultpresets from an external preset is not supported. I'd like to added some preset links to the default highway presets to my Presets/LaneAttributes presets if it is installed and active.
