[XeTeX] Latin Modern name changes: important warning

[Mojca Miklavec]

Hello,

This is a rather important warning. LM fonts are about to change their
names (both filenames and their proper names) soon.

This means that:
- fontspec needs to be prepared for that
- you will need to update both simultaneously if you want to be able
to use LM in Xe(La)TeX

I have no idea what that means for XeLaTeX, but ConTeXt will (is) be
broken in either case (new fonts & old ConTeXt or old fonts & new
ConTeXt) independent of whether you use LM or not.
