Fairly major update to php code generation and type library. Brief summary:

- Revised simplified makefile generation using -make switch.
 - Proper support of in, out, argout, ret typemaps.
 - Function overloading with typecheck typemap support.
 - Fragment inclusion in typemaps.
 - Proper handling of object destructors relying on PHP's reference counting.
 - Constants using consttab and varinit typemaps.
 - Global variables using varinit typemaps.
 - Can generate C++ bindings using either objects or no objects (-noproxy).
 - Special phppointer.i typemaps for using php references for pointer passing.
