Like the Visual Studio 2008 project files, split up the property sheets
so to ease maintenace, and to prepare to use autotools to fill in the
header entries to "install".
Put some of the items that are frequently repeated in the projects as well,
also to simplify maintenance.
Also, update the autotools files to automate the upgrade of Visual Studio
2010 project as we now have multiple property sheets to copy and process.
Add the PlatformToolset tag to the project configs so that we can use add a
simple script later to the autotools files to copy the projects and change
the value (v100 -> v110) of that tag (and other simple changes) in order
that we can quickly provide and maintain support for Visual Studio 2012
with minimal effort.
Note that at the moment GLib does not yet support the API/SDK requirements
for Windows 8 Modern UI (formerly known as Metro), but this paves the very
initial step.
Get rid of _CRT_SECURE_NO_WARNINGS and _CRT_NONSTDC_NO_WARNINGS
from the preprocessor definitions as those two macros are now defined
in msvc_recommended_pragmas.h, which is force-included in these projects
via the property sheets. This will silence C4005 warnings on macro
redefinition.
-Seperate intermediate directories for each project to avoid intermittent
MSBuild errors that a build log cannot be written while in use, and
update the property sheet as necessary.
-Minor cleanups of uneeded tags in the projects/properties
These tools require the use of GModule headers also, so update the include
directories so that the correct gmodule.h will be included instead of the
system-installed version.
-Added projects to compile the glib-compile-schemas and gsettings utilities
-Update .vsprops to install these in "install" phase
-Distribute these projects also
