Correct handling of ORM::Model::Field objects in ORM::Clause-s and inside arrays.
Can manually specify connection clause in joins now.

$f -> connect_filter( $f1,
		      _clause => $clause );
Very flexible opertaion when connectint filters with clauses containing fields from different models.
More tests.
Do not try to find matching attr when connecting clause is explicitly specified (test27).
Extended test.
CPAN package update.
We're not so simple anymore, now we're quite flexible and powerful.
