Improved PUTC and fix minor glitch

PUTC only goes to the next line if a \n is send
Also, new line now wraps if the end of screen buffer is reached.
Fix type on monitor parser
Monitor partialy working

Print last address working
Run at lasr address working
TODO :
 - Print address range (BEXAM mode)
 - Input data mode (STORE mode)

ISSUES :
 - PUTC ('\n') should clear the rest of the line ?
 - Floppy data not being loaded. Could be a issue on firmware or virtual
   hardware...
