Added findSites() method which uses Lucene queries to retrieve sites.
This method supports a CONTAINS query on cm:name, title, description.
All listSites() methods are now immediately consistent - as opposed to eventually.
However in moving these method implementations to CannedQueries, they now only
support STARTS_WITH_IGNORE_CASE queries on cm:name, title, description.
I've highlighted this in the javadoc.
ScriptSiteService now uses the eventually consistent findSites() method for searches.
Also some fallout in the tests.
