function mediafront_update_6004 in MediaFront 6

Same name and namespace in other branches

1. 6.2 mediafront.install \mediafront_update_6004()

I know this is a crazy update, but there is a reason.

We are now using the views styles to add the presets to each view instead of the UBER-HACK of adding "Media Player Page" and "Media Player Block". Now all you do is just add a new "Page" with a style of "Media Player". This is a MUCH more elegant solution and makes the code crazy simpler. So, instead of just killing every install out there for this upgrade when I blow away the old method, this script will now convert the old method to the new method.
