Command line tools

* Added base classes for all importable data. These new classes should
be used for all future loaders; all existing loaders that are modified
should be updated.

* I18N loader rewritten to make use of the new base classes. External
strings are now read using the XML data file's path as the base
directory.

* Updated all external I18N definitions and moved the existing files
around in an attempt to make the data directory somewhat more livable.

* Added dependency management entry for the server's main package to the
root project, updated server distribution package accordingly. Added
dependency on the server's main package to the server's testing package.
