Now that C++11 is required, I'm removing the C++11 annotations from things in

the documentation.  I also updated a few places throughout the docs to say that
you need a C++11 compiler.

-         The deep learning toolkit in dlib requires a C++11 compiler.
-         Unfortunately, as of July 2016, no versions of Visual Studio fully
-         support C++11, so not all the deep learning code will compile.
-         However, all the other modules in dlib can be used in Visual Studio
-         without any trouble.
+      <question text="Why can't I use the DNN module with Visual Studio?">
+         You can, but you need to use Visual Studio 2015 Update 3 or newer since prior versions
+         had bad C++11 support.  To make this as confusing as possible,
+         Microsoft has released multiple different versions of "Visual Studio
+         2015 Update 3".  As of October 2016, the version available from the
+         Microsoft web page has good enough C++11 support to compile the DNN
+         tools in dlib.  So make sure you have a version no older than October
+         2016.
