Add tooltips across buttons in interface to help tutorialize use

[brettfiedler]

Can use the Tooltip from react-bootstrap/Tooltip to use OverlayTrigger on buttons.

CameraMain.js for example

<OverlayTrigger placement='left' overlay={<Tooltip id='tooltip'>Click to toggle the sidebar</Tooltip>}>
<Button
  onClick={() => this.setState({ sidebarOpen: !this.state.sidebarOpen })}
>
  {this.state.sidebarOpen ? '☰ Close Sidebar' : '☰ Open Sidebar'}
</Button>
</OverlayTrigger>

Will work on adding this to other buttons across the interface.
