MALstats v0.86.5

Some changes
User history graph watching/completed/dropped/on-hold lines are now on the same scale and now show how much you completed or dropped that week instead of your overall number. The graph also looks a bit nicer now.
User passwords are now not stored permanently, only while they're in the queue waiting to be processed, where they're encrypted as well. How my updater worked before was it'd delete your list off your DB and then just repopulate it based off your MAL's XML because that was the simplest and easiest way to do so. Now that passwords won't be stored, the daily updates would erase any data that needed a user login to access (Episode history, rewatch data), so I changed the updater to now update existing entries, which leaves episode history and rewatch data intact.
