  Kill floating_point_emulation.hpp with fire (#713)

Ability to emulate floating point calculations makes sense only if we
intend to support platforms without native floating point support. Such
platforms haven't been relevant since mid-1990s or so. Besides, supporting
such platforms would require converting the entire codebase to use the
tfloat class instead of native float and double types, which would be
outright Herculean effort.

As a bonus, killing floating_point_emulation.cpp also eliminates two uses
of boost::enable_if_c.

I also removed the nonexistent file SDL_SavePNG/savepng.hpp from the
Visual Studio project, and added #include <string> to
formula/debugger_fwd.hpp because the build failed otherwise
(maybe compilation order changed when I removed
floating_point_emulation.hpp?).
