G_IMPLEMENT_INTERFACE warnings

[DindinX <dindinx gimp org>]

  Hi,

  The G_DEFINE_TYPE* macros are very handy to reduce the typos while
creating new classes. I now use them in the gimp and some other
personnal projects.  However, using the G_IMPLEMENT_INTERFACE macro
introduce a warning when compiling with -W.  This is not that important,
but it can be fixed easily.

  The attached patch fixes this.

     Can I commit it?

     Regards,

         DindinX
