EOL at EOF.
Replace ${version} with ${project.version}

The former is deprecated.
The code makes use of commons-io; explicitly declare the dependency.
Fix compilation error; the java collection is raw.

Previous code seems to have picked up a version (via a transitive dependency) which returned a non-raw collection.
Convert some of the code which uses commons-io to use Guava.
Upgrade to the current version of rpki-commons: 1.0.37
