Commented Unassigned: Reduce package.config files to only the current compiler version [285]

The package.config files currently cause VS to download both the 110 and 120 versions of Boost. Since we've separated the project files (and they can have separate package.configs) we should only require downloading the NuGet packages relevant to the user's version.
Comments: Fixed in the development branch. Now vcxproj's only pull in the NuGet packages they actually need :)
