Implement the campaign overview tab

[scottbenton]

The campaign overview tab should be available when the campaign type is not solo. It should include the information that the GM needs to run the game.

The left sidebar should include:

• Campaign Overview
  • A spot to change the game name
  • A spot to change the campaign type
  • A spot to copy an invite link for other players to use to join
  • A list of the current players in the campaign
• Assets section - ONLY visible if the campaign has any shared assets (starship for example)
• Tracks section - same as on the character sheet

The central pane should include campaign notes

The right pane should be the same as on the character sheet.

If #11 is complete, make sure the same mobile changes apply here.
