Added escape condition checking and handling code.

Detail:
  escape_check returns R0:0 as the escape condition flag (returned in
    C flag from OS_ReadEscapeState).
  escape_check_ack will acknowledge an escape condition if one exists
    (OS_Byte 126)
  escape_check_clear will clear an escape condition if one exists
    (OS_Byte 124)
Admin:
  Built.

Version 0.08. Tagged as 'AsmUtils-0_08'
