Re-implemented the install-build-deps.sh script file, so that on 64 bit
systems we build and install proper Debian packages instead of directly installing files into the filesystem. This allows the user to cleanly uninstall the packages and it prevents corruption from us accidentally overwriting files that the system tries to manage itself. Also, the script now installs debugging symbols where available. This allows gdb to step into system libraries. The developer still needs to download the actual source code with "apt-get source" and point the debugger to it.
