Multi-Multi-Filter for collections page functions

In perch_content_custom and perch_collection, you can choose the operand for filters in the page function: 'match'=>'or'.

It would be a nice touch to runway if you could combine filters with OR and AND in the same "query". Something like this:

'filter'=>array(
    'filter'=>array(
      array(
        'filter'=>'some',
        'match'=>'eq',
        'value'=>1,
      ),
     array(
        'filter'=>'other',
        'match'=>'neq',
        'value'=>'',
      ),
      'match'=>'or',
    ),
   'filter'=>array(
      // either it's an original
      array(
        'filter'=>'more',
        'match'=>'eq',
        'value'=>'lorem',
      ),
      array(
        'filter'=>'evenMore',
        'match'=>'eq',
        'value'=>'ipsum',
      ),
      'match'=>'and',
    ),
    'match'=>'or',
),

=> WHERE ('some' eq 1 OR 'other' neq '') OR ('more' eq 'lorem' AND 'evenMore' eq 'ipsum')
