* Added FileObject.copy().

* Renamed <v-copy> task attributes file -> srcfile, tofile -> destfile, todir -> destdir.

* Moved provider instantiation out of DefaultFileSystemManager, and into
  myrmidon-aware VfsManager.  Providers are instantiated using the TypeManager.
  The list of providers isn't configurable yet.

* Some support for %nn encoded URI (not quite complete).

* Zip file system now handles zip files from any file system, not just local
  files.  Still read-only at this stage.  Uses a truely dodgy and very temporary
  replication mechanism.

* Zip file system now handles relative paths in URI (e.g. zip:relpath.zip), that are
  resolved against the base dir.

* Fixed bug in resolving names against the root file of a file system.

* Changed behaviour of FileName.resolveName( ".." ) for the root file of
  a file system.

* Added more test cases.

* A bucketload of other minor changes.
