[PATCH 0/1] MR5234: win32u: Add registry keys for changing media center/tablet status.

[Aida Jonikienė (＠DodoGTA)]

This is a heavily simplified version of Michael Müller's staging patch
(the staging version got broken by the PE/Unix split)

I rebased that staging patch but I thought it was too big for what it
does (so I did this instead)

As for automatically changing the status, SM_MEDIACENTER would require
Windows version checks (which are never used in Wine) and SM_TABLETPC
would likely require touchscreen/tablet detection (rbernon is working
on some touch stuff so that could be useful)
