Remove non-existent wx/cairo.h from MSVC{11,12} projects.

This file resulted in never ending rebuilds of the core project as MSVS tried
to recreate the missing dependency (and failed).

See http://blogs.msdn.com/b/andrewarnottms/archive/2012/06/07/enable-c-and-javascript-project-system-tracing.aspx
for help with debugging such problems in the future.
