Add ability to selectively publish certain builds to selected hudsons

We started using your plugin and it is great, but it wont work with our approach
until a new feature gets added. We have many projects that all use a core asset
developed by one group. We would like every hudson on every project to build
this core asset in their own environments, then all will publish back to the
core asset hudson so that he can aggregate all the results into one dashboard
view. This works fine with the plugin, but now we have 2 core assets, so I want
all hudsons to publish job A to hudson A and job B to hudson B.
