Add the new Orbis chat as a module to the Cadastre

[gravenp]

Description Add the new Orbis chat/feed as a module to the Cadastre. This will provide another interactive mode for Cadastre users. This is helpful especially as the Cadastre is desktop-only currently.

Requirements

• Add a chat icon to the header of each parcel details panel (next to the Open in Spatial Browser icon)
  • Material Design "Chat" icon (https://fonts.google.com/icons?icon.query=chat)
  • Tooltip/hover text = "Open Parcel Chat"
• Clicking this icon should open the parcel-specific Orbis feed in a new lightbox (utilize same method as https://github.com/Geo-Web-Project/browser/issues/86)
• User must be signed in to Orbis to post comments
  • For now, this sign-in will be separate from the wallet sign-in required for Geo Web transactions
