[Live-demo] Re-categorising OSGeo-Live projects

[Cameron Shorter]

Categorisation is only ever going to be a rough best guess that won't 
fit all cases, but better to have than nothing. It is also based on user 
perception. If my main purpose for rasdaman is to run SQL queries on it, 
then I'd categorise it as a DataStore. If it is largely used for WPCS 
and WPS, then Web Services is better.

I still have a mild preference for categorising Rasdaman as a Web 
Service, but will keep the categorisation as Data Store unless Peter 
tells me otherwise.
