Disable Toggle Comment when Editor is not visible

[lorenzncode]

There is a new Toggle Comment item under the Edit menu and shortcut key. I'd suggest to disable the feature when the Editor widget is not visible for users of external editors.

@lorenzncode Is there a functional reason to do this (i.e. it causes a problem), or is it more of a user experience reason (i e. It causes confusion)?

@jmwright It's more for user experience (nothing major). Since I'm not using the editor I'd prefer only the viewer options to be presented or enabled. Then I can safely ignore editor features and no chance I might comment something out that is not visible. I guess it would only comment line 1 if I were to trigger it accidentally.
