Rename the install projects to clutter-install so that it would be easier
to use the project file set as a part of a grand solution file, such as
one that is used to build the entire Clutter stack.
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.
...and drop these project files, as the way how the conformance
tests are built has been totally reworked. Instead, in the future,
use NMake Makefiles to build them, which will be proposed later.
