Remove -cppcast and -nocppcast command line options

Browse source 
The -cppcast option is still turned on by default. The -nocppcast option
to turn off the use of c++ casts (const_cast, static_cast etc) has been
removed. However, defining SWIG_NO_CPLUSPLUS_CAST will still generate C casts
instead of C++ casts for C++ wrappers.

This a revert of commit fc79264a48:
"Revert "Remove -cppcast and -nocppcast command line options""

The Scilab and Javascript casting problems are now fixed, so -cppcast
is now switched on as default.
