Patchwatcher status: regenerates configure, notifies authors on failure, filtered patches mailing list

[Dan Kegel]

Patchwatcher now regenerates configure and makefiles
after each patch, so it can handle patches that change
configure.ac.

I have enabled email notification to authors of patches
that don't build.

The script now forwards patches that pass all tests to the mailing list
http://groups.google.com/group/wine-patches-filtered
so potentially Alexandre could start looking only at that
list (though it probably only has two nines of reliability at
this point, as patchwatcher doesn't handle every case yet,
e.g. it doesn't handle partial resends of patch series).
