SRAMP-451 S-ramp maven facade for fuse fabric

https://issues.jboss.org/browse/SRAMP-451
This introduces a vector for an injection attack.  You cannot create criteria this way - you need to use the form:

@maven.artifactId = ?

And then the value of ? has to be provided to the sramp query object.  Since there are only two variants of the query (a query with 4 clauses and a classifier query with 5) you should probably just have two static queries and pick the one you want based on the presence of the classifier.
