- [NEW] La posició del cursor se marca amb un requadre blau (no relleno) en el desensamblador

Browse Source 
- [NEW] setcursor corregeix l'adreça si no coincideix amb una instrucció
- [FIX] Corregits els opcodes FD34 i FD35
- [NEW] Ara en el analitzador es borra o es fixa la memòria amb DELETE i RETURN
- [NEW] Fent click en un pixel del analitzador du a la posició de memòria que toca en el desensamblador
- [NEW] ui::printvoidrect()
- [NEW] la finestra del analitzador pilla el foco nomes amb pasar per damunt
- [NEW] Fent click en una linea del desensamblador fica o lleva un breakpoint en eixa adreça
- [FIX] les accions en el analitzador actualitzen la finestra del debugger
- [FIX] El cursor del analitzador nomes es deu moure al estar damunt de al finestra del analitzador
- [FIX] El desensamblador, quan el tag de memoria era MIXED no reconixia part de la instrucció
- [FIX] El desensamblador usava el color incorrecte per a codi amb el tag REPEAT
