gbuild-to-ide: VSGenerator and testVs2013 with relative links

VisualStudio2013IntegrationGenerator  recently doesn't work
with the new relative paths in GbuilParser.
this patch does this, now it works fine with all relative paths.
what is missing it's in the .vcxproj:
<NMakeBuildCommandLine>
<NMakeCleanCommandLine>
<NMakeReBuildCommandLine>

these still work with absolute path but i start now on working this
