Comments editor: Disable insert link until focused

Browse Source 
Comments editor: The Insert Link button has no effect until the user
clicks inside the comments box, therefore disable it until it is ready,
to prevent confusion. Fixes #1208073 [Insert Link not working](https://bugs.launchpad.net/calibre/+bug/1208073)
