Title: Added support for identifiers in JOINs

We need identifiers in JOINs, e.g.:

$select->columns(array('id'))
->from($this->table)
->join('user', 'image.user_id = user.id AND image.user_id = :userId', array(), Select::JOIN_LEFT)
->where($select->where->isNull('user.id'));

This patch allows to use identifiers like :userId in joins.
