Makefile has again a make install target. The install targets
are split because it is easier for the rules file to install
the files for the different packages inside different destinations
directly.
- Modified debian/rules to create both relational and relational-cli from the same python file
- Modified relational_gui to have different behavior depending on its name
- Do not try to pack examples directory for relational package
- Edited make source target
