Query generator should not treat quoted phrases specially.

Browse source 
Quoted strings in CQL only have syntactic meaning for the parser, they don't carry semantic meaning for the resulting query.

As a consequence of this change, they have to be used in their unquoted form (`tok2.getString()` instead of `arg2.toString()`).

NOTE: The `cql.unmasked` relation modifier may be implemented in order to support the previous behaviour of "protected" phrases.
