Windows fix + Sorting based on list

This fix introduces changes so that development can be done (and tested) on other platforms than Linux. This is a convenience fix and shouldn't break anything (simply a few Linux-specific imports that have moved into the functions where they are used).

This commit also introduces sorting based on a list of priorities (where the default will be last if not matched).
