GetFeatureInfo for WMTS Layers

Currently GetFeatureInfo (GFI) only works for WMS (and WFS/Vector) layers. WMTS 
also allows the GFI service, provided that the backend WMTS server is able to 
support this. Within the Dutch PDOK project there is a need to support WMTS GFI 
, in particular to view feature info of BGT layers (large scale topography). 

Similar to WMS GFI WMTS GFI needs to be enabled via the Layer configuration. 
This implies that also the Heron Context XSD and XML needs to be aware of WMTS 
GFI. openLayer supports WMTS GFI via the OpenLayers.Control.WMTSGetFeatureInfo 
class, similar to WMS GFI control.

Within the Heron core framework the following adaptations are required for WMTS 
GFI:

1- FeatureInfoPanel class: create/handle both WMS and WMTS OpenLayers GFI 
Controls. Should follow the same patterns as WMS GFI.

2- FeatureInfoPopup class: handle WMTS GFI/Control 

3. ToolbarBuilder class: adapt the featureinfo button entry (pre-creates 
Controls e.g.)

4. Heron Context: adapt XSD and XML config handling (mapping config to the 
creation of Layers with parameters). In particular use the 'queryable' config 
parameter in addition to the featureInfoFormat parameter. The 'queryable' 
parameter is also compatible with GXP.

5. Example: extend the existing WMS featureinfo examples with WMS layers

6. App: extend the app/pdokviewer application config to enable WMTS GFI for 
some PDOK layers

It is assumed that all rendering using the existing featurePanel will work as 
expected, i.e. no changes required.
