Linking structures to their AST nodes to have access to their positions (#534)

* Linking several structures to their AST nodes to have access to their positions

This far there were only 3 types of structures linked to their AST nodes. Now adding some more expressions and literals to their AST node to have access to their token's position in the query.

* Added missing parts in JSQqlParserCC.jjt for AST linking to work

Added missing parts in JSQqlParserCC.jjt to make sure all relevant code is created to generate and link AST nodes to the relevant structures.
