Making it more convenient to create WMTS layers from capabilities documents. The format now has a createLayer method that takes a capabilities response object and a layer configuration object. This returns a properly configured WMTS layer based on the layer and matrix definition found in the capabilities. Unless otherwise specified, the layer name will be derived from the advertised title, and the style identifier will be the advertised default. r=ahocevar (closes #2676)
