Firefox 4: Flat, "Chrome-like" buttons

/*
"Flat" toolbar buttons, ala Chrome.

Preview: http://otakubooty.com/me/johnbooty_userchrome.jpg

If you want to play around with userChrome.css, I recommend:
  1) https://developer.mozilla.org/En/DOM_Inspector - identify, inspect, and tweak chrome elements in realtime
  2) https://addons.mozilla.org/en-us/firefox/addon/quickrestart/ - or any other "add a restart button to Firefox" extension

/*
Opacity can be adjusted to taste. Changing to
0.8 from the default of 1.0 makes icons them
blend in with the toolbar color a little more.

Removing the borders has the (subjectively) beneficial
side effect of making the buttons take up a little
less horizontal real estate, as well.

Adds some empty space between the tab
browser and the windows min/max/close buttons in
the upper right.

Otherwise, there is little to no empty space
on the toolbar to allow you to drag the window.
