Disable Gmail "Add to Circles"

Disables the Google+ "Add to Circles" buttons in Gmail.

Removes the "Add to Circles" button in Gmail that Google+ has added in. These buttons normally appear on mouseover of a contact's name. All it takes is accidentally mousing over one to activate it (for example, while your mouse is on its way to the "Emails" link for a contact), which rolls out a list of Circles, covering up whatever UI was underneath it. If you then mistakenly check one of those Circles, you've just sent an awkward Google+ invite to that contact. Uses a simple CSS selector and no JS, and restricts itself to load only on Gmail pages, so it shouldn't harm performance. Gmail and Google+ are trademarks of Google Inc.
