Feature request: extend `%header.set()%` to accept multiple addressees

[RealRaven2000]

To simplify usage, the commands header.set(to), header.set(cc) , header.set(bcc) could be expanded to accept multiple addressee parameters, like this:

%header.set(to,"address1","address2","address3")%

The address parameters can be the usual name <email address> or email address

Currently you can only achieve multiple recipients by using a combination of commands like this:

%header.set(to,"address1")%
%header.append(to,"address2")%
%header.append(to,"address3")%

It will also make sense to allow multiple parameters to %header.append()% - in order to keep the original recipient in a reply template and add multiple recipients in a single line.

To install version above download zip file and drag the file into Thunderbird Add-ons Manager (do not extract contents, it won't install like that)

This new feature worked perfectly for me! Thank you for taking the time to address my issue referencing multiple addressees!
