Better chain rules for import and compilation.

Added intermediate targets in the rules file to manage link the process of
importing routines to the process of compiling routines.
Point Vcs-Browser and Vcs-Git to alioth.

Set the URLs for locating the Git repository in Alioth.
Reorganizing build vs config targets.

In rules, reorganized build vs config. Leaving in the build target the process
of importing routines and globals, followed by the process of compiling all the
routines.
