Build with Visual Studio 2012

It's more aggressive about enforcing that keywords are not macros
in C++ mode, and has bumped the MFC version to 11.

Keep compatibility with older versions of Visual Studio, appropriately
conditionalized.

WiX support for building with VS 2012

Hack that works on VS2012 but not VS2010

The merge modules need to reference VC110 paths.
Use a variable for minimal text expansion.
Require Windows Installer 4.5 or higher

As advised by the VC 11 merge modules.

Windows Installer 4.5 requires Windows Server 2008, Windows Vista, Windows XP
with Service Pack 2 (SP2) and later, or Windows Server 2003 with Service
Pack 1 (SP1) and later.  I believe we already enforce these restrictions
manually elsewhere, so this should not restrict our set of valid target
machines.
