v0.5.1

What's changed

• Running a query uses Ctrl+R (or F5) instead of Ctrl+Enter; some terminal emulators,
  notably on macOS, intercept Ctrl+Enter for their own context menu, and report
  Shift+Enter as a plain newline.
• Saving or testing a connection fills empty login and password fields from credentials
  embedded in the URI, so a pasted connection string works without the From URI button.
