Black&White Project/Automatic compilation/configure

In order to ease maintenance and readability of this very essential script in the build process, we have decided that configure.ac needed a major rewrite. Because this script cascades everywhere towards the compilation chain, we will work on the rewrite in parrallel.

To use the new compile script, do the following:

./autogen.sh alt

The configure.ac does not exist anymore in svn. A link to configure_orig.ac (previous version) is created by autogen.sh.
