Subject: JS: Moved and rewrote VN relations editor

+ Some fixes and improvements in the dropdown search
+ Renamed 'relations' field to 'vnrelations', as other relations are
  going to be implemented as well

New relation editor code is somewhat smaller than the old, mostly thanks
to the tag() function. Also tried to make things less error-prone and
easier to maintain by referencing things using self-explainable class
names instead of the ordering of the HTML tags.
