eclipse/ant -> maven

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.
