Introduce a new query component and example

[adube]

GSGMF 1047 - phase 1

This patch is the first step towards implementing a new way to query the map by drawing polygons.

This patch introduces:

• a new QueryModeSelector service that:
  • will replace the QueryKeyboard service
  • stores the mode of the queries, i.e. "click", "draw_box", "draw_polygon"
  • stores the action of the queries, i.e. "add", "remove", "replace"
  • listens to the keyboard key pressed to temporarily change the mode or action
• a new <ngeo-query> component that:
  • will replaces the <ngeo-map-query> and <ngeo-bbox-query> directives
  • uses the new query mode selector
  • uses a Draw interaction to draw the boxes (instead of DragBox in the original mapquery directive)
• a new ngeo "query" example that features the component, in which you can see it in action, with all the modes enabled

Limit option

There is a limit option that can be set in the ngeoQueryOptions angular value.

There is also a ngeo-bbox-query-limit attribute that can be set in the `ngeo-bbox-query.

As part of this refactoring, I suggest that only the limit option in ngeoQueryOptions should be used.

autoclear option

There is a ngeo-map-query-autoclear attribute that can be set in the ngeo-map-query directive. It was added as a possible "binding attribute" in the new component.

I'm mentionning it, because we do have ngeoQueryOptions and it could go there instead. If you think the option should go there instead, please let me know.

Update: it was decided that the autoclear option should go in the ngeoQueryOptions instead. This will come in an other PR.

Next step

The next step will be to remove the 2 old directives, examples and replace the query tool in all examples (ngeo, gmf) and applications (gmf).

@sbrunner Would you please give me hits how to fix these issues:

src/query/component.js(102,15): error TS2314: Generic type 'VectorSource<Geometry>' requires 1 type argument(s).
src/query/component.js(311,25): error TS2339: Property 'feature' does not exist on type 'Event | Event'.

@adube I've pushed a commit that should fix the typing checks

[adube]

@fredj or @sbrunner any idea why Travis is complaining?

Thanks Fred for the fixes btw

[fredj]

the travis error is not related to your changes. I've restarted the build

[sbrunner]

@adube The CI pass :-)

[adube]

Alright! This is ready for review, then.

@fredj I'll take care of moving the "autoclear" option of the component to the ngeo.QueryOptions angular value in an other PR.

This is ready for review.

looks very good, thanks
