(Xojo Plugin) Load .eml and Decrypt (smime.p7m)

Loads an encrypted email from a .eml file and decrypts using certificate w/ private key found in a .p12 (or .pfx) file.

The Content-Type and Content-Disposition email headers of the email to be decrypted look similar to this:

Content-Type: application/x-pkcs7-mime; smime-type=enveloped-data;
	name="smime.p7m"
Content-Disposition: attachment; filename="smime.p7m"

// The email now exists as it was prior to encryption.
// Your app may access the email's subject, body, attachments,
// etc. using the Chilkat Email API...

// Save the decrypted email:
