Merge branch 'master' of github.com:ox-it/maps.ox

* 'master' of github.com:ox-it/maps.ox:
  Removed rooms from maps.ox categories
  Added museum category now we show children based on structure
  Get children from parentcat attr
  Set "parentcat" attr depending so we can child categories
  List categories by the plural name
  Now the root category isn't necessarily '/' so get root node
  Reset collection if categories are in configuration, else fetch.
  Add categories to maps.conf
  Updated cat parser to read type_prefixed from the API representation
  Fixed bug where multiple requests were being sent on position:unpaused
