DEB build scripts: several enhancements as follow:

- major rework of update_repositories.sh script, which now supports
multiple branches and provide better feedback to user.
- added support for pre-built extra dependency packages. A user can now
use Slavek Banko's binary packages instead of building the extra
dependency locally. This removes a quite tedious process during the
setup of the building environment.
- bug fixes and more user friendly folder names.
- improved README to cover the complete process until TDE installation.

Special thanks to Gregory Guy <zadig83@laposte.net> for testing and
feedback done so far.

@@ -168,18 +207,19 @@ C) How to use the scripts
 1) Follow the steps in section "A) Environment preparation" (only required the first time).
 2) cd "TDE_DIR/buildscripts"
 3) Update to latest git repository using
-   ./update_repositories.sh
-   Wait until "Update completed" is printed out. Check log in TDE_DIR/0_logs/ if you wish.
+     ./update_repositories.sh
 4) Run "sudo pbuilder update" at the beginning of the day to update the base package to the latest version. This will speed up
    the process when building several modules in sequence.
 5) Build modules as per your needs. You don't need to use "sudo" directly since the scripts will do that automatically if
    required. Just type your sudo password when prompted to do so.
 6) Create a local repository from the packages you have just built, to be used as installation repository. 
-   Add the following lines to /etc/apt/sources.list and follow the usual way to install TDE.
-		 # --- LOCAL TDE REPOSITORY ---
-		 deb [arch=<YOUR ARCH> trusted=yes] file:TDE_DIR/3_repo <YOUR DISTRO> main
-	 For example:
-		 deb [arch=amd64 trusted=yes] file:/home/tde_src/3_repo buster main 
+     [sudo] ./create_repo.sh
+7) Install TDE as you usually do. For example as follow:
+     - sudo apt-get update
+     - sudo aptitude install tdebase-trinity   (for a minimalistic TDE environment)
+         or
