Sistemare makefile in modo tale da creare la cartella bin non all'interno di src

[StefanoMunari]

1. move makefile in root dir
2. tidy-up c_src : enforce "simil-package" tree structure - related to #5
3. move bin/ + obj/ in root dir
4. add run command to makefile (to run the FAC binary)
5. add profile command to makefile (for valgrind memory debugger and profiler)
6. add example command to makefile (to exec all the examples)
7. add PRINTER flag to makefile (use it as argv input for FAC)
8. add VGOPTS flag to makefile (use it to set valgrind options when profile is executed)

TODO

6. add example command to makefile (to exec all the examples) => need all the examples fixed
7. add PRINTER flag to makefile (use it as argv input for FAC) => need a switch to choose the printer in parser.y

6. Prerequisistes done. (At least the examples/ex*.f)
