[server.rqlannotation] rename SQLGenAnnotator to RQLAnnotator
This class is in charge of annotating the RQL syntax tree with
various bits of information, like (in)variance, use of
full-text-index, etc. It is a needed step before the generation
of SQL, but does not touch SQL directly. Hence RQLAnnotator
seems a better name.
