"Add" Visual Studio 2015 projects by what we did before: Copy the Visual
Studio 2010 project files and replace the items in there as needed, as
the formats of the 2010 and 2015 projects are largely the same.
We need to rename the projects so that when these projects are added
into an all-in-one solution file that will build the GTK+ 2/3 stack,
the names of the projects will not collide with the GTK+-2.x ones,
especially as GTK+-2.x and GTK+-3.x are done to co-exist on the same
system. This is due to the case that the MSVC projects are directly
carried over from the GTK+-2.x ones and was then updated for 3.x.
We still need to update the GUIDs of the projects, so that they won't
conflict with the GTK+-2.x ones.
Rename the "install" projects as "gtk-install" as we are planning to have a
grand solution file that incorporates all project files of the GTK+ stack
with their dependencies, to make it easier for people to build GTK+ from
scratch from a stock installation of Visual Studio 2008 and later.
This utility would likely be useful for Windows builds of GTK+, given the
reasons Alex cited for coming up with this utility[1], and MSVC build
support for librsvg is not available at this time (possible, but not
implemented yet).

As the Visual Studio 2012/2013 are only slightly different from the Visual
Studio 2010 projects, we can provide support for them by using scripts to
copy the Visual Studio 2010 projects, and update the specific parts as
necessary.
Thus, there would be little maintenance overhead for these as only the 2010
projects need to be kept up-to-date as a result. This might change when we
do get the stack working with WinRT/Metro, but that's going to be another
totally different issue.
