Changes because `FileUtil.copy()` was renamed to `FileUtil.copyAll()`
Fixed #1759 The Ceylon `copy` tool should be updated with the latest artifact types.
Also changed `--all`to really copy all know artifact types, not just the one the tool knows about.
And we now ask the CMR for directory types instead of hard-coding that information.
Fixed tests because of ceylon/ceylon.language@d19116bc2bc3bb0e9d9d147654d274948a97a575
Minor clean-up of imports
Added support for setting the resource directory for compiling and running Ceylon tests
Added resource folder entries to `TestModule`
