release: 3.0.1

Bump the workspace to 3.0.1 and bring the user guide up to date: an RDP
chapter, shell integration and inline images, SSH certificates and CAs,
known_hosts import/export, stored credentials and master password change,
profile sync (replacing the Alchementary Link migration chapter), the
Diagnostics tab and log, and refreshed screenshots throughout. The welcome
screen's protocol line now lists RDP.
