Added different counter query support for Doctrine_Pager. Now it can use 2 different queries to paginate items. Added 4 new methods: setCountQuery, getCountQuery, setCountQueryParams and getCountQueryParams. If not defined a counter Doctrine_Query, the collector one is used. If no params were defined to be used in counter query, the ones passed by execute method are used
