Split up the property sheets, so that they are easier to maintain, and
clean up the projects and property sheets, especially on items that are
being repeated, and therefore silence many build warnings. Update the
project files correspondingly, and make all project files use Unix line
endings, for easier application of patches (the .sln and README.txt files
still has to have Windows line endings in order to work properly).
Also make the copying of config.h.win32 and clutter-config.h.win32(_GDK)
custom build rules, so that they may also be cleaned during the cleaning
of the build, which makes it easier for one to do a rebuild.
Similar updates to the Visual Studio 2010 project files will follow.
-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
Apparently the update to build the GDK backend broke the "installation"
process of the binaries. Fix that by grouping the binaries as Release or
Debug.
