refactoring the feature node blocks - 2 + adapting test suite
adapting test to changes in r19676 : implementing rule 2 and 3 for #3904 (EuroMed: Implement filtering rules for Distributions) - all existing test running successfully
adapting test to new situation after adapting portal to refactored distribution tree implementation in cdmlib
fixing tests for nameUsedInSource implemented, this leads to semi-duplication of footnotes since some are without name in source data while other are without
fixing #2349 (order of common names in dataportal confused) and upgrading selenium to 2.33.0
common names orderd and merged in case of duplicates
adapting test to current situation - unclear what has caused this: one foot note in the distribution seems lost Afghanistan 20,21 ??
