Add query component

Enjoy review @gjn :)

[test](http://mf-geoadmin3.dev.bgdi.ch/dev_query_2/)

Bug known:
 -  [x] attributes doesn't updated  on translate change in some case.(Fixed)

- [x]  ExtendedTooltip print is not working
                 
- [ ] help page



But the `globals.selectionShown` element using ga-collapsible-show is a div (and therefore without href attribute). The old ga-collapsible-obvserve connected to the element. Any reason you can't here?

Don't know the use cases here but it could lead to a regression on page load (state of the layermanager maybe)

Also, either use ga-collapsible-observe for globals.selectionShown or remove ga-collapsible-observe completely (as it's not used anymore)
