Windows vcproj patch

["D.J. Heap" <dj...@shadyvale.net>]

This is where I got to with the vcproj generator -- I've rebuilt it to 
patch against r5928.

You can probably tell I'm fairly clueless with Python (most of the code 
changes I stole from the dsp generator, and it's probably a naive way to 
do things), but these changes allow me to build the libraries and 
compile the exe's -- the exe's still don't link unless apr.lib, 
aprutil.lib, apriconv.lib and libneon.lib are manually added, although I 
have linked several of them by doing just that.

Obviously, I haven't done anything with the external projects that need 
to be added to the solution (and appropriate dependencies changed).  I'm 
not sure what to do, really...see my earlier post under the Building on 
Windows thread.
