Split Makefile into several makefiles

Since before the merge d6d2908 (huge
GUI refactorization), the old API of Julia interfaces offered to call
the GUI. Since, this merge is was not possible since Petri net and GUI
have been separated. It's now a better idea to have 3 libraries: - core
for managing Petri nets without GUI; -- GUI for editor using Petri nets;
-- Julia interface.
