[patch] fix delete key on certain european keyboards

[zhilla]

reposting this here, looking for someone to fix a long standing wine bug.

text [edited] again:
well, this is just this:
http://bugs.winehq.org/show_bug.cgi?id=2400
and should apply to today's cvs.
i AM NOT the author!

it IS kinda urgent, since a lot of european keyboards are affected...
like hungarian, croatian, slovenian... all have "delete" key producing 
"<delete>,"
  instead of "<delete>". this patch is just a "works here" workaround, 
see url for more details.

i got response from some people, so i fixed comments, but what needs to 
be tuned, according to mr. Dmitry Timoshkov, is that it should use 
symbolic key(sym) names instead of hardcoded numbers. seems like a 
trivial task for a programmer (which i am not)
so, anybody up to it?

Changelog:

   * dlls/x11drv/keyboard.c

     This fixes the problem is that when NumLock is active, both Del 
keys perform a "delete" action _and_ insert a comma (the decimal character).
