Take service domain name from Cytoscape Properties

[bdemchak]

In case someone decides to stage the Diffusion service elsewhere (yay!), we need to allow them to do so by taking the service domain from a configurable source. If the property doesn't have a value, it's OK to default to our hard-wired domain name.

Now the property is called diffusion.url in standard Cytoscape property.
