A couple ideas for 4.5 Marketplace

[RocketStang]

I've been testing out the 4.5 Marketplace on my test board and a couple small ideas for improvement came to mind...

1. Add a filter to show all FREE items.

2. Mark or identify items that the user has already INSTALLED in the Marketplace!

Thanks for looking!

A price filter, just like have in Store, would be very nice too.
