Title: Change SqlWalker property visibility

I'm working on a library to add support for spatial data types and functions to Doctrine. I'm trying to implement a custom AST walker which will return objects from DQL queries instead of scalar values. I've currently gotten this to work but the implementation feels a bit hack-ish:

With the visibility on the SqlWalker class properties changed it allows for what I feel is a cleaner implementation:

https://github.com/djlambert/doctrine2-spatial/blob/sqlwalker-visibility/lib/CrEOF/Spatial/ORM/Query/GeometryWalker.php

I'm only using the ```$rsm```, ```$scalarResultCounter```, and ```$scalarResultAliasMap``` properties, but I changed all of them with the thought that someone else might find the others useful.
