Previously just the Dispose() method was generated.
Now the Dispose() and Dispose(bool disposing) methods are generated.
Changes are required if custom "csfinalize", "csdestruct" or "csdestruct_derived"
typemaps are being used. Details in #421 on Github. SWIG will error out if one of
the "csfinalize, "csdestruct" or "csdestruct_derived" typemaps are found. Example
error message:
foo.h:60: Error: A deprecated csfinalize typemap was found for Foo, please remove
it and replace all csdestruct, csdestruct_derived and csfinalize typemaps by the
csdispose, csdispose_derived, csdisposing and csdisposing_derived typemaps.
Closes#421
