Context indicator changes

[bbondy]

• Change the connected to page UI to be less confusing. It will now be a toggle underneath and glued to the input box. Default to ON
• If the user turns it off, remove the Summarize this page button
• After context is included in a conversation the switch should disappear and it should go into the scrollable history instead.
