Plug/Socket bug workaround patch commited

[Maciej Stachowiak <mjs eazel com>]

It's in (thanks to Martijn for fixing some weird merge breakage for me).

Time to release Bonobo 0.7 now? :-)

PS For what it's worth, Miguel, it's a bug fix, not an
optimization. In-proc components couldn't be drag and drop targets the
old way because plug/socket are broken for the local case.
