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 <[email protected]> for testing and
feedback done so far.
