Changeset 184 in xtideuniversalbios for trunk

Message:

Space optimization, added a new format character 'I' which is the same as 'u' but shows a dash if the operand is zero. Replaces the PushIRQ functionality in bootmenuprintcfg.asm. This only saves a few bytes now, but saves significantly more with the string compression code.
