Make Eclipse happy.

Updated the Eclipse classpath entries to reflect the dependency
management changes. The Eclipse plugin for Ivy can be obtained from
http://www.apache.org/dist/ant/ivyde/updatesite.
Removed the use of classes deprecated in JUnit 4.

According to the friendly manual[1], no class from junit.framework
should be used.
