[tex-hyphen] new patterns: Piedmontese

[Mojca Miklavec]

Hello,

I just wanted to let you know that I added Piedmontese hyphenation
patterns to the repository.

Once the author (Claudio Beccary) confirms that everything is OK, I
can submit the new version to CTAN.

I could also include an experimental version of Thai patterns
depending on author's preference. If anyone has any other request,
please let me know. One thing that's on the TODO list is removal of
hyphen.cfg, but that needs a bit of testing and maybe it should better
be changed during the freeze period of TL.
