Add an "Open in Box Drive" UI option for the web app.
This solves the problem of identifying a file or folder in the web app, wanting to work on the file or folder in Box Drive, and needing to leave the Web App to navigate through several steps to find that file in Box Drive.

Ideally this should only be active on hosts that have Box Drive installed; it could be not presented, or disabled, on other hosts.

For hosts that have Box Drive installed, this would allow:
1. When activated for a folder, that folder as presented by Box Drive will open in the native desktop file explorer (Explorer or Finder).
2. When activated for a file or file preview, that file will open in the native desktop app, loaded through Box Drive. Identifying the application to load the file would be done using the desktop OS's file association mechanism.

This would complement the existing Box Drive "View on Box.com" functionality.
