Overhaul the Visual Studio 2008 Projects

Give the Visual Studio 2008 Projects an overhaul, and clean them up in the
process by consolidating commonly-used items in property sheets, so to ease
future maintenance.

	* MSVC_Net2008/pangomm-build-defines.vsprops:
	* MSVC_Net2008/pangomm-version-paths.vsprops: Add property sheets
	  to group together commonly-used items so that the projects can
	  refer to them, so to ease future maintenance.
	* MSVC_Net2008/pangomm/pangomm.vcproj:
	* MSVC_Net2008/gendef/gendef.vcproj: Move to MSVC_Net2008/ and
	  clean up using the property sheets, and update the file paths
	  accordingly.  Stop building blank.cpp, as the IDE recognize the
	  .cc sources, and stop using the /vd2 option, as it is a source
	  of weird crashes.
	* MSVC_Net2008/pangomm.sln:
	  MSVC_Net2008/filelist.am: Update file paths accordingly.
Overhaul The Visual Studio 2010 Projects

Give the Visual Studio 2010 Projects an overhaul, by using property sheets
to consolidate commonly-used items, and moving all the projects to
MSVC_Net2010.  Also stop using the /vd2 compile-time option, as it is more
harm than help here, since it causes weird crashes.

	* MSVC_Net2010/pangomm-build-defines.props:
	* MSVC_Net2010/pangomm-version-paths.props: Add property sheet
	  sheets to consolidate commonly-used items items so that projects
	  can refer to them, which will help to simplify future
	  maintenance.
	* MSVC_Net2010/gendef/gendef.vcxproj:
	* MSVC_Net2010/gendef/gendef.vcxproj.filters:
	* MSVC_Net2010/gendef/pangomm.vcxproj:
	* MSVC_Net2010/gendef/pangomm.vcxproj.filters: Move to
	  MSVC_Net2010/, and clean up using the property sheets.  Adjust
	  the source file paths accordingly, and remove the /vd2 compile-
	  time option as it brings more trouble than help.  Add
	  PlatformToolset tags so to ease future move to Visual Studio
	  2012/2013.
	* MSVC_Net2010/filelist.am:
	* MSVC_Net2010/pangomm.sln: Update file paths accordingly.
MSVC 2008/2010 Projects: Add "Install" Projects

This adds "install" projects for Visual Studio 2008/2010 builds so that the
build results can be copied to a common directory together with the
dependencies, so that testing and packaging will be made easier.

* MSVC_Net2008/pangomm-install.vsprops:
* MSVC_Net2008/install.vcproj:
* MSVC_Net2010/pangomm-install.props:
* MSVC_Net2010/install.vcxproj: Add MSVC projects and property sheets to
  copy build results to a common directory under the root build directory.
* MSVC_Net2008/pangomm.sln:
* MSVC_Net2010/pangomm.sln: Include the "install" project in the build
  process.
* MSVC_Net2008/filelist.am:
* MSVC_Net2010/filelist.am: Include the added projects and property sheets
  in dist.
