Debian Support

The structured publish was failing on architecture=all type packages before.

I fixed that by appending architecture=all type packages to all architecture specific package inecies (Packages files).

However, the simple publisher instead appears to publish a dedicated "all" package index. Unless I am mistaken this is also the preferred best practice method for current Debian repositories. (Should be researched further).

We should decide which version we want and use it consistently across both (non verbatim) publishers.

We could also consider making this configurable? This might be helpful in case older APT clients cannot handle dedicated "all" package indecies?
