Rubernate 0.1.5

This release includes support for Postgre SQL and a lot of minor fixes and improvements. Performance is still poor but it is going to be better in future releases.

Some issues have been found:
Functions Rubernate::Queries::Operations::IsNil and IsNotNil behaves incorectly in some cases. So query like this

  q = Rubernate::Queries.query 'Select :o; Where IsNil(o.p1)'
  puts q.to_sql

will produce following sql

  select o_.* from r_objects o_ left outer join r_params o_p1 on (o_.object_pk = o_p1.object_pk)
    where o_p1.name = 'p1' and o_p1.name is null

That has wrong condition where o_p1.name = 'p1' and o_p1.name is null is never true. So until this issue resolved, queries like that should be writen using native sql.
