Introduces UI and logic to handle password-protected certificate files. The CertViewerControl now prompts for a password if needed, and attempts to reload the certificate with the provided password. Refactored certificate loading flow to support this feature.
Introduces QuickLook.Plugin.CertViewer for viewing certificate files (.pfx, .cer, .pem, etc.) in QuickLook. The plugin loads and displays certificate details or raw content, and is integrated into the solution and project files.
