The solution files which are updated due to the split of Cogl-Path need
to be pushed as well, which were forgotten. Sorry about this, and fix
.def file generation on Cogl with SDL on Visual Studio 2010 builds.
Since commit 7253c5ca (Bug 682071-cogl/cogl-sdl.h: MSVC: Link to SDL when
apps are built), on Visual C++ we link to SDL.lib and SDLmain.lib using
a #pragma comment directive in cogl/cogl-sdl.h, so we no longer need
specific project configs for Cogl programs which build against a Cogl built
with SDL. This removes those unneeded configs.
Also "install" cogl/cogl-sdl.h when Cogl is built with the SDL winsys, as
it is a needed header
-The test program and examples must be linked to SDL too when COGL is
built with the SDL renderer, so add configs accordingly.
-Also use Multibyte character sets (i.e. don't -DUNICODE) for all configs,
like what GLib does, for consistency.
-Fix the VS2010 property sheets that was accidently malformed.
