S/MIME Internal Implementation
[*] When using S/MIME internal implementation and a user removes a self-signed certificate with private key from account, The Bat! also deletes this certificate from Trusted Root CA address book.
[-] (#0006784) Signing certificate wasn't saved as default while signing (using internal S/MIME).
[-] (#0004656) When signing a message with S/MIME internal implementation, and the "OK" button was inactive because the user had the only one self-signed certificate, after clicking "View" and adding this certificate to the "Trusted Root CA" address book, the "OK" button was still inactive. The user had to click "Cancel" and then try to sign the message again.

Secure Connections
[*] During the TLS handshake, The Bat! first looks for certificates in the address book, and then, if a required certificate was not found there, in the list of certificates transmitted from the server to the client during the TLS handshake. It allows the user to add proper certificates to the address book to override the troublesome certificates that might have been transmitted by the server.
[*] Better logging for certificate chains in TLS connections.

Templates
[+] %MEMO template macro for including the original message's Memo text.
[+] New syntax of %ABnnnEMAIL macros: it is now possible to retrieve secondary email addresses on an address book entry by passing a number as the first parameter, e.g. %ABOTOEMAIL(1). The second parameter can be used for setting the default value. %ABnnnEMAIL[="Default Value"] work as before and in the same way as %ABnnnEMAIL(0, "Default Value").
[-] %CLEAR macro did not work in HTML/Windows Editor.
[-] (#0006987): %ISSIGNATURE pasted many times in HTML.
[-] (#0007004) Links (http or mailto) does not reformatted to clickable when pasted from a Quick Template.

[-] If a submission form preview couldn't sign or encrypt the form contents, an empty error box was shown.
