Introduce river mapfile generation (WARNING: Changes in config xml files required!).
On startup the RiverMapfileGeneratorStarter is called by the server app.
The starter invokes a call to RiverMapfileGenerator.generate() which
reads all available rivers from the database and generates
layers for each river (in theory...uncompleted) in a
river.map file.
The old MapfileGenerator which generates layers that have
artifact dependencies is now in ArtifactMapfileGenerator.
