Replace remaining legitimate usages with [Keyed]DialogProviders.
Remove the DialogManager itself, all the getters for it, all the places keeping
references around to it, all the dialogs taking it in the constructor, and all
the partridges in pear trees that had one hidden away.

This fixes the issues with injection of dialogs and the behaviour of @Singleton.
Move the swing injection related classes into a new package (a new DialogModule
will follow shortly to make use of the DialogProvider).
Also introduce a SwingPreconditions class for asserting method calls are made
on/off the EDT.
