Remove support of VS2010

[pmiossec]

because I can't build it anymore (On my machine and on AppVeyor)

What are the implications of this change? Is it that only users of TFS with VS 2012 or later can use this version.

If I'm not wrong.... it depends....

Since VS2015, dlls required to support a new version of TFS is provided by nuget package.
So, if git-tfs can't load the different VS dlls, it will fall back to this and it should work with earlier version of TFS (but I'm note sure because not tested with TFS2010...).

Except if your TFVC collection enabled checkin policies. Because if that's the case, you should absolutely use the version of VS corresponding to the version of TFS (to be exact, git-tfs should be able to load the VS dlls corresponding). So, if you have TFS2010 with checkin policies enabled, you will have indeed to use the last version of git-tfs supporting VS2010.

But I hope that you no more use the very old version of TFS2010....

Fortunately we don't use check-in policies, unfortunately we do use TFS2010!
