Consider immediate support for VS2015 when it is released

[Zingam]

As Microsoft it pushing for massive Windows 10 migration in the near future and this means VS2015. Consider supporting the new version right out of the box on release.

Yeap, I think I can handle support for VS2015 and once the MSBuild-auto-update feature is in place and working, selecting and migrations betwen Visual Studio versions from 2010 - 2015 should be straightforward and as easy as installing new plugin from Extensions Gallery.

Please refer to my fork, if you like to have more features or improvements.
