Added refresh function

Added a function to refresh current items

This could be useful, but DIM already has an auto-refresh that happens (though I think it's been off since KF raid launch) in the background. I've actually logged an issue related to switching characters in-game then attempting to move an item via voice. It will usually fail until you either reload the page or hit the manual refresh (circling arrows in top right). I think the refresh itself could be useful if we can detect that a transfer/equip/store should have happened but didn't; however, I think it's overkill as a command.

Since the KF launch and the API issues, I find myself having to refresh manually before doing what I would want to use the extension for which I feel defeats the purpose. Other times I want to get the refresh started because I know I'm about to go through the loot I just got but that was more of an issue when it could take up to a minute.

I guess I don't see how this is overkill but turning farming mode on and off and equipping the max power loadout isn't.

Because auto-refresh is off right now at the behest of Bungie. It should be back on soon.
