-Combine entries in the property sheets and make it a bit more flexible,
and drop some redundant items
-Use Custom Build Rules for generating enumeration and marshalling sources,
and the .def file so that they can be wiped off when a "clean" is
requested, and regenerate automatically when the templates/.symbols
files are updated.
-Improve consistency by using ApiVersion rather than ClutterApiVersion
with the Visual Studio project for other components of the Clutter/GTK+
stack
-Get rid of unneeded configs in the "install" project
-Make things a bit cleaner by generating clutter.def in the intermediate
build folder
-Fix the include paths as config.h is now in clutter/
-Make things a little bit more consistent between vs9 and vs10 in terms of
the "install" stage
-Add configuration in Clutter projects to add option to build Clutter with
the GDK3 backend in addition to the Win32 backend
-Add another preconfigured clutter-config.h.win32_GDK which contains
backend configs for both GDK3 and Win32 windowing and input.
Update output DLL/LIB names to be consistent with the autotools output,
due to the newl-introduced multi-backend feature (only the Win32 backend
is supported here for now, GDK3 support will be added when it stabilizes)
