While it adds an annoying depth to the actual source code, it makes
the root directory nicer (no more 'test-res' dirs), means we don't

* Move resources out of source trees
* Add Gradle build scripts.
* Remove ivy and ant build scripts.

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.
