Mostly some cleanups.

Also added two experimetal functions, Ouvrir_popup and Fermer_popup, and started to implement a (commented) example popup menu for selecting freehand draw mode.
But it seems there are problem if doing a while(Mouse_K), Mouse_K seems to be reset when the mouse moves, or in some other place. Time to sleep so i'll continue that tomorrow.
