Various Visual C++ support updates

Various Visual C++ support updates

-Move the stub stdint.h back into the vs9 folder as stdint.h is shipped
 with Visual C++ 2010, and update the corresponding Makefile.am's
 accordingly
-Add new solution to build Pango with FontConfig-the former solution file
 will build Pango without FontConfig.  This is to simplify the use
 of the GTK+ stack as many will probably not use FontConfig on Windows,
 therefore this is to reduce the number of dependencies
-Added configurations in Pango, PangoWin32, PangoCairo regarding FontConfig
 (To make sure their configurations are consistent across the board)
-Cleaned up the various project files for a bit.
