Subject: [PATCH] On Windows, check file name case with 'sound' and 'music' CON
 commands.

This is done by kopen4loadfrommod'ing and immediately closing the file
(since the checker is still run from there when not ingame).
On my system, times were like 0.12 ms, 0.2 ms and 0.5 ms for each
openfrompath/findfrompath, openfrompath/Bopen and SHGetFileInfo
respectively, so it shouldn't have a too noticable impact on initial
loading times.
