- [NEW] Configuració per a compilar i depurar des de vscode

Browse Source 
- [FIX] Meimades per a que es calle el compilaor al dir-li -Wall
- [NEW] Reestructurats els simbols, 6502dis probablement acabe desapareguent
- [NEW] Reactivats els breakpoints i next (pas a pas sense entrar en subrutines)
- [NEW] Nou motor de desensamblat
- [NEW] Ja es mostren tots els simbols en el desensamblat
- [NEW] Syntax colorets en el desensamblat
