Should expose current bot URL somewhere in the UI

[tonyanziano]

Is your feature request related to a problem? Please describe.

When connecting to a bot via URL -- not .bot file -- there is no UI indication of what URL the bot is running on. This can be an issue when launching a connection to a bot via URL through a deep link (such as testing your bot via Composer) and wanting to know the URL for debugging purposes.

Describe the solution you'd like

The current URL for the livechat session with the bot should be visible somewhere in the UI (maybe in the tab title?).
