extensions: add "uipopulate" hook, called per instance, not per process

In short, this is the "reposetup" function for ui. It allows us to modify
ui attributes without extending ui.__class__. Before, the only way to do
that was to abuse the config dictionary, which is copied across ui instances.

See the next patch for usage example.
