Update questions and glossary items that refer to onion icon or torbutton

There is no longer an onion icon in TBB release 9 and the term torbutton appears to be even older. The following items still need to be updated:

• -How do I view Tor Browser message log?

Also:

• "-I am having trouble connecting to Tor, and I can’t figure out what’s wrong." (not clear 'please select the option to "copy Tor log to clipboard."') It used to be in the torbutton but...

Glossary items:

• "NoScript

Tor Browser includes an add-on called NoScript, accessed through the “S” icon at the top-left of the window, which allows you to control the JavaScriptthat runs on individual web pages, or to block it entirely."

(there is no S icon)

• "Tor log

"Tor log" is an automatically-generated list of Tor’s activity that can help diagnose problems. When something goes wrong with Tor, you may see an option with the error message to "copy Tor log to clipboard". If you don't see this option and you have Tor Browser open, you can navigate to the Torbutton (on the top left of the browser, to the left of the URL bar). Click the Tor button, then open Tor Network Settings. You should see an option at the bottom to copy the log to your clipboard, which you can then paste to a document to show whoever is helping you troubleshoot."

(refers to Torbutton)

• Torbutton

A button marked by a little gray onion to the right of the URL bar. Its menu offers you "New Identity", "Tor Network Settings..." and "Check for Tor Browser Update..." options.

(remove or mark as historical?)
