Merge pull request #7 from Tillerino/modularMaven

Switched to maven project.
- Eclipse files have been removed from repository. jar and native dependencies have been removed from repository.
- Use maven goals "compile exec:exec" to run the project.
- Use maven goals "package shade:shade" to create a single jar file, which contains java, but not native dependencies. This jar file can then be used with jarsplice to create a fat jar. Natives will be extracted to /target/natives.
