* Added "dummy" data file for technologies (for now it simply copies the
old, line-based technologies) and corresponding XML schema
* Added missing SQL stored procedure to clear all dependencies and
reverse dependencies from a technology
* Added import classes, loader and import tool for the technology graph
* Added tech graph import tool to post-build tests
* Implemented resource definition loader including tests
* Added resource definition xml file and style definition
* Made a small style change to i18n loader
* 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.
