Visual Studio has an environment variable named PlatformArchitecture that evaluates to "32" for 32-bit builds and "64" for 64-bit builds. There are many places in the Windows build where we have written obj32, bin32, or lib32. Many of these can be replaced by obj$(PlatformArchitecture), obj%PlatformArchitecture%, etc.
I had some trouble with the .sh shell scripts, work-around-vs-dependency-tracking-bugs.py, and copyForwardingHeaders.cmd, so those can be done in a separate patch. This is a large step towards getting a 64-bit build on Windows.
I also had some trouble with WebKitExportGenerator. To prevent this patch from being too large and complicated, I'll do the rest in another patch.

This patch has some quirks. It puts some things (a build log, some scripts) into an obj directory instead of obj32.

This needs more work before it's done, and it would completely break the 64-bit build until it is done.
Let's do this in small steps, starting with the vxcproj, props, and filters. They work without modifying behavior on the 32-bit build. It will destroy any hopes of manually hacking together a 64-bit build until we're done, but I'm the only one who's doing that right now, anyways.

I got carried away with my regular expressions. This needs to be done manually.

I forgot to undo my changes to a .make file in the previous patch. This one's good.

Yuck! Visual Studio project files are the worst. This looks fine to me.
