Investigate tiled=true for WMS 1.3.0

[nf-s]

We add tiled=true for WMS version 1.1.x but not 1.3.0.

We should look into this and depending on GeoServer configuration - GeoWebCache will only be hit if tiled=true.

GWC might only support WMS 1.1...

There's a few paths to get caching in Geoserver:

1. Using the "direct integration" (which gets GeoServer's WMS and caches that)
2. Using the GWC URLs (which goes direct to GWC)

When using 1, there's a setting in GeoServer that says "explicitly require tiled parameter" and if that's false, then you must pass in the tiled=true parameter to get caching. It's probably a good idea for Terria to add tiled=true always, as there's no downside.

When using 2 this isn't a problem, as it doesn't support version 1.3.x...
