[RFC] convert the script into modules

[boredsquirrel]

It would be pretty easy to make the script load other scripts. That way we could split it up, as I think it mixes up thread models a lot.

a main script loading the modules (you can comment out the lines)

• general
• stay anonymous
• no html and images
• ...

best example is

• time zone
• dictionary
• time settings
• convert sender time to UTC

this does not make sense for many people, but instead would break workflows. Imagine Thunderbird in a company.

I'm rather in favor of keeping the template "close to" upstream, for maintainability purpose. Sorry if I seem boring about this, but the idea is to keep things simple as I have a pretty limited bandwidth (EDIT : and that I'm actually alone to keep this up to date).
