djutils v2.1.8

pom file has only one test-resources entry. Originally, test-resources contained both /src/main/resources and /src/test/resources, to make the resources also available to the unit tests. The latest version of Eclipse, however, cannot deal with two locations. Since we already copy the resources with Maven, having both locations is not needed.

Dependency on djunits has been updated to v5.0.2.

CLI test that failed on 100.0erg/g for an AbsorbedDose has been repaired by adding a space between the value and the unit. An issue in djunits should resolve this issue.
