VS: Add version year to generator names

Rename the Visual Studio >= 10 generators to indicate the version year:

 Visual Studio 10 => Visual Studio 10 2010
 Visual Studio 11 => Visual Studio 11 2012
 Visual Studio 12 => Visual Stduio 12 2013

Report the names with the year to the list of available generators so
that the cmake-gui drop-down shows the years.  When selecting a
generator from the "-G" option or from an existing CMAKE_GENERATOR cache
entry, recognize names without the years for compatibility and map them
to the names with years.

Update the generator names in the cmake-generators.7 manual.

+Visual Studio 10 2010
+---------------------
+
+Generates Visual Studio 10 (VS 2010) project files.
+
+It is possible to append a space followed by the platform name to
+create project files for a specific target platform.  E.g.
+"Visual Studio 10 2010 Win64" will create project files for the
+x64 processor; "Visual Studio 10 2010 IA64" for Itanium.
+
+For compatibility with CMake versions prior to 3.0, one may specify this
+generator using the name "Visual Studio 10" without the year component.
