Standardized path for Cinder library in .vcxproj

In order for the project to compile, the cinder_0.8.5_vc2010 library
folder must be included at "C:\Libraries\". (Unfortunately, there isn't
really a better way to handle this across multiple computers, short of
sticking the whole 600 MB library in the Git repo...if you want to keep
yours elsewhere and are concerned about disk space, ask me about
symbolic links. :-))
