Missing XONLINEN string/flag for XOnline library

[RadWolfie]

I recently discovered XONLINEN, library name string, appear in Exhibition Demo Disc Volume 05:

• "Rallisport Challenge 2" demo (5849 LTCG)
• "Ninja Gaiden" demo (5659 LTCG)
• "Shadow Ops: Red Mercury" demo (5849 LTCG)

Further investigation is needed to verify if existing signatures are compatible with XONLINEN library. Plus add more titles that were overlooked.
