This commit re-organizes all the source distribution contents to present users with the simple script, while moving the rest in extras. Also autoconf/automake scripts were removed, back to minimalism. The rationale of this change is that Tomb really only consists of a script and users with no extra needs should just be presented with it with no need for anything else. Any other thing on top of the Tomb script is an extra and can be even distributed separately or integrated in distributions.
