Many changes towards a unified initialization and startup procedure, unification of
ModuleService and EntityContext. All schema configuration is now handled by a
dedicated Configuration object so this information can be obtained from different
sources, not only the Structr JARs etc. More changes to come, work in progress.
Again many changes towards a better configurability of structr and its core
parts, moving configuration entirely into the structr.conf. Added automatic
UUID creation, removed UuidCreationTransformation in abstract base classes,
many changes, work in progress.
Removed some old classes and packages, many modifications towards a unified configuration
file, work in progress w/ failing tests and compile-time errors.
Added visitor pattern to Service interface in order to allow Services to
augment the default configuration from a module context. Modified WebSocket
code to obtain Authenticator from HttpServiceServlet, work in progress.
Modified Service interface to use StructrConf instead of Properties class
consistently.
Added common Structr Service class to replace module Main classes, modified
Services class to obtain resource JAR from structr.conf entries, added
HttpServiceLifecycleListener to be able to listen to server start and stop
events.
Added SERVER_IP again.
Renamed ModuleService to JarConfigurationProvider, renamed Configuration
interface to ConfigurationProvider to better reflect the actual semantics.
Added resource handler handling out of new configuration scheme
