[PATCH 5/6] comctl32/datetime: Use locale data to compute field widthes for day and month

[Nikolay Sivov]

Control should be flexible enough to respect locale day and month (at least)
names.

Another major problem here is genitive month name support. I tested with russian
locale for this patch and it really uses a genitive form. This data is missed
from current locale definitions and as far as I can see there's no way to
retrieve it even after addition. A bug http://bugs.winehq.org/show_bug.cgi?id=18466
exists for that.

Changelog:
    - use locale data to compute field widthes for day and month
