  Fixups to type trait aliases

* Apparently, even VS 2013 includes the general type alias templates. Allow their use there.
* Removed broken C++11 value alias templates (values aren't even allowed this fashion).
* VS 2015 Update 2 apparently both introduced support for variable templates and added them for type traits. Updated accordingly.
* Blocked off the entire variable template section until we bump out min compiler version, since there's no way to implement
  them without variable templates.
