Sieve "foreverypart" and "mime" extensions (RFC 5703) now implemented

Hi,

I have finally managed to implement the Sieve "foreverypart" and "mime" extensions (RFC 5703). These are now included in the main Mercurial repository and will be included in the next release.

I will be fixing a few minor details in the coming week; e.g., interaction with "include" and "editheader" extensions needs more work. Still, in the mean time, those of you who are interested can already test this feature a bit. It is not a small feature, so knowing bugs early is helpful. You can install it from the Mercurial repository or get the latest Debian packages from Xi.

When I finish the last details (probably next week), I will release a first RC version of Pigeonhole v0.4.10 right away.

Regards,

Stephan.
