Gideon/fixed feature funtion test

Fixed FeatureFunctionTest, which was no longer working properly as a consequence of change 
casing of the feature name in LabelCombinationFF.

Also adapted the .classpath, removing the mockito / testng source and javadoc entries, which are not automatically 
fetched by apache ivy and give problems in eclipse.
(An alternative would be to add them somehow in ivy.xml, but I don't know exactly how to do that and if they are actually at all needed/used)
