Final solution for nightly builds

Well, after several attempts to and from and here and there, we have finally landed in putting all the nightly builds (including the deb file repository) on tuxfamily.org. This is a well-connected site and they didn't seem very bothered about the network load. This means we're ditching the other attempts for hosting nightlies (for example google code, launchpad and sourceforge) so please stop trying to download the nightlies from there if you started.

I have update the instructions for downloading a tarball and for setting up apt to install makehuman. Please review these and report any problems here or on the forums.

As a side note, with the advent of the tuxfamily hosting, we definitely have space and capacity for builds for other architectures, platforms and distro versions. A MacOSX nightly build anyone? :-)
