Adds a button to the Owned Caches page to toggle between hiding/showing archived caches
This script adds a button to the Owned Caches page to toggle between hiding/showing archived caches. It also makes the header more useful by mentioning the number of active caches.
Aesthetic bug: the zebra coloured background pattern gets messed up when hiding archived caches (the script just hides rows with an archived cache in them). If anyone really needs it, I'll make a fix.
