introduce Query#joinOn( '', $table, $a, $b ) to obtain a normal where condition
introduce Query#joinOn( '', $table, $a, $b ) to obtain a normal where condition

In this way I can use:

	Query::factory()
		->joinOn( '', 'a', 'a.id', 'b.id' )
		->getQuery()

To obtain:

	SELECT * FROM a WHERE a.id = b.id

Instead of running:

	throw InvalidArgumentException( 'not enough tables' )

Note that this feature was introduced for better lazy handling of nested queries.
