Github

I decided to move the addon from sourceforge to github.

The rational behind is to make life for contributors as well as bug tracking easier. Nevertheless it's more limited and more commercial than sourceforge, which is the down side.

The source code's new home is now at https://github.com/thsmi/sieve .

Also the Sieve reference moved from mozdev to github. You find it at https://github.com/thsmi/sieve-reference .
