Allow X509 files opened from the file system to be displayed in a UI similar to the certificates view

[odalet]

When one opens a file in CertXplorer, the file is opened in the ASN1 viewer and only in it. It'd be great if X509 files could open in an UI similar to the Certificates tab. This way we could examine all its properties the same way as for X509 objects in Windows Certificates Store.

One way to do this would be to create a "virtual" Certificate Store named "File System" for example where dropped files that are X509 (or similar: csr for example...) would appear. Then they would appear in the same tab as other certificates.
