Extend InfoClick support

[Hallbergs]

While i was updating the config for our demo environments i found that some WMS providers returns strange responses from getFeatureInfo. See image below for an example:

These responses are not rendered correctly in the FeatureInfo-window since we expect the id to be constructed as
<layerName>.<some-numeric> when we try to grab the necessary information for the FeatureInfo-window from config. In the case above, another random numeric is added to the id...

I am gonna try to sort this out, and hopefully this fix can be added to the 3.11 release. I'm a bit afraid it can't be added though, since it will probably be quite big changes since the logic around the FeatureInfo is...

Great initiative with fixing the config and fantastic upcoming solution.

Let's see what it feels like after the Hollidays: whether we go for a quick merge to upcoming release or take some time to untangle this spaghetti.
