Adds a simple refresh button (tab) to the Devtools window.
Why? Sometimes you just want a refresh button in your devtools window instead of moving your hand from chin to keyboard for a `cmd + R`. Or maybe you're so deep into devtools with _many_ windows open and you simply can't quickly navigate to the current inspected window.

Just a really nice tool to stop me from being driven insane resetting my inspect window each time I make a minor CSS tweak. Would be cool if there was a refresh button in the tab as well as sometimes I won't always inspect the page in-between changes so you have to click off the tab and then back but that's a minor frustration all in all. Thanks for this one! :)
