Factored some #ifdef noise out of the initialization function by adding

SwigPyBuiltin_SetMetaType.

For %import statements, move the runtime import out of SWIG_init and into the
.py file.  The reason for this is that the import must be executed within the
python execution frame of the module, which is true in the .py file, but *not*
true in the initialization function.  Had to re-order the .py file slightly
to put the 'import' statements at the top; that's necessary to make sure base
types from an imported module are initialized first.  If -builtin isn't used,
then the .py code is not re-ordered.

Added an explanation and workaround for the limitation that wrapped types are
not raise-able.
