Several major changes around jodconnector:
* The created project now has the jar in it to build more easily
without Eclipse
* The jodconnector source code is now in the source tree instead of a
jar. The means that the jar is created at build time.
* Removed the SLF4J dependencies from the jodconnector
* Removed the JODContainer as it's now useless
Started to implement a better export wizard, similar to the JAR export
wizard from JDT. Took that occasion to refactor some parts of the
Language extension point to make it cleaner.
