Remove jquery edition of metaquery

The jQuery edition of metaquery arose because Mr @paulirish challenged that metaquery could be even smaller, and at the time jquery was still in wide use (although, not by me).

It made little sense to actually release the jquery edition back then, and even less sense to maintain it today.
