[ckan-dev] Allow CSW harvesters to define CQL filters

Ciao Adrià,

Sure.

For testing I used mainly GeoNetwork instances, which deal with cql filters 
quite well. 
I used the opendata instance of the city of Florence:
   http://datigis.comune.fi.it/geonetwork/srv/en/csw

You can use this configuration to filter out a single record:
   {"cql": "title LIKE '%zonizzazione%'"}

A sample query was already in the issue #55 I guess.

   Ciao,
   Emanuele
