Modified WINE's winmm.dll to support loading of user-installable drivers

Browse source 
from the registry 'Drivers' and 'Drivers32' keys, as Windows does. Also 
silenced the beep-MIDI driver (which is supported by winmm! - but 
doesn't seem to do much, at least under vmware.)

Added some Drivers32 entries to be loaded by default, to the hivesft.inf 
file.

MME User-Mode Driver Support
(c) Andrew Greenwood, 2007.
This is intended for use with WINE's winmm.dll to allow it to find
and load appropriate drivers from the correct (Windows) registry keys.
By default, WINE's winmm.dll will look in:
HKEY_CURRENT_USER\Software\Wine\Drivers
Here it determines the driver to load based on a value called "Audio".
Windows NT stores a list of drivers in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
