Title: Update Q class for nullable=True

* Update match check in constructor to check for None since False is a
valid value for nullable
* Updated query builder for neo4j version 2 queries that check for null
values (in cypher 2 NULL = NULL evaluates to false, and "is/is not
null" construct must be used).
