Add Google+ link to frontpage
Added version 0.23.0 - Gargamel - to apt repo
Added all official and unofficial Debian archs

Added all architectures from http://www.debian.org/ports/ to the NIPAP
apt repository.

Fixes #436
Added packages to new repos
Add Flask-XML-RPC and Flask-Compress to deb repo

Flask-XML-RPC and Flask-Compress are prerequisites for the Flask backend
for NIPAP. While the Flask backend is still a proof of concept, it is
nearing being good enough to replace the old Twisted backend. Including
these libs as they are not available in usual debian repos and we need
some way of getting them.

Kind of part of #273.
Added Flask-XML-RPC and Flask-Compress packages

They're in the extra section. Needed for the new Flask backend and since
they are not in standard Debian repos we add them here :)

Kind of part of #273.
