Copy cmGlobalVisualStudio11Generator to cmGlobalVisualStudio12Generator
and update version numbers accordingly. Add the VS12 enumeration value.
Add module CMakeVS12FindMake to find MSBuild. Look for MSBuild in its
now-dedicated Windows Registry entry. Teach the platform module
Windows-MSVC to set MSVC12 and document the variable. Teach module
InstallRequiredSystemLibraries to look for the VS 12 runtime libraries.
Teach tests CheckCompilerRelatedVariables, Preprocess, VSExternalInclude,
and RunCMake.GeneratorToolset to treat VS 12 as they do VS 10 and 11.

In commit 485a940e (VS: Simplify MSVC version reporting, 2012-08-23) we
accidentally flipped the 0/1 values of MSVC_IDE. Flip them back and
teach the CheckCompilerRelatedVariables test to check the variable.
Teach the CheckCompilerRelatedVariables test to verify MSVC11. Update
the special cases already in the Preprocess and VSExternalInclude tests
for VS 10 to work for VS 11 too.
Some HPUX compilers give this error: Error 690: "/home/cport/Dashboards/My Tests/CMake-build/Tests/CheckCompilerRelatedVariables/main.cxx", line 1 # Nonempty source files must end with a newline that is not preceded by a backslash.
