As with commit 11397eb6dd, use $(TargetDir) and $(TargetName) for the
Import Library output rather than $(OutDir)\$(ProjectName)d.lib and
$(OutDir)\$(ProjectName).lib.
Carrying on from commit 11025613b9 added VC10 project files which are
capable of supporting side-by-side compilation, 32-bit and 64-bit
builds as well as support for some of the third-party libraries curl
uses.
