mk-ca-bundle: Update the vbscript version
Bring the VBScript version more in line with the perl version: - Change timestamp to UTC. - Change URL retrieval to HTTPS-only by default. - Comment out the options that disabled SSL cert checking by default. - Assume OpenSSL is present, get SHA256. And add a flag to toggle it. - Fix cert issuer name output. The cert issuer output is now ansi, converted from UTF-8. Prior to this it was corrupt UTF-8. It turns out though we can work with UTF-8 the FSO object that writes ca-bundle can't write UTF-8, so there will have to be some alternative if UTF-8 is needed (like an ADODB.Stream). - Disable the certificate text info feature. The certificate text info doesn't work properly with any recent OpenSSL.
