[winecfg] - drive editing to use volume management functions

[Chris Morgan]

The drive definitions have been moved out of the ~/.wine/config file and into 
the filesystem and registry.  The volume management functions modify drives 
are now supported(thanks Eric and Alexandre).  Having winecfg use these 
functions makes the drive dialog useable for editing drive mappings, 
something we need before we can turn winecfg loose on end users.  Feel free 
to try this patch out and report how it works.

* programs/winecfg/winecfg.c, winecfg.h, resource.h, En.rc, Makefile.in, 
drive.c

Implemented an array of 26 drives and interface functions for adding, copying, 
moving and deleting drives. Added a "Show/Hide Advanced" button in the drive 
edit dialog that toggles the display of advanced options and resizes/moves 
controls.  Disable the 'autodetect' radio button in the drive edit dialog 
until we have autodetection support. Map window 'x' button to dialog close.

Added PRINTERROR() to call GetLastError(), translate into a plaintext message 
and print via WINE_TRACE().

Comments, questions?

Thanks,
Chris
