EDIT

fixed possible NPE and handling of null values

reintegrated campanula drupal branch

cdm_feature_block_element_tag_name() incorporates value set in feature_block_settings['element_tag'] and further fine tuning of feature block settings

fixing #1803 (PALMS. Common names entered with Editor not displaying well in the portal), the CommonName elements respect the feature block settings so that source references as content are shown in the portal

fixing #3704 (show name in source for Distributions) for all cases (nameUsedInSource & originalNameString) as well for all settings options: sorted and unsorted distributions with or without bibliography block

refactoring the handling of annotations, sources and name in source information. cleaner and simpler code, less complex statements and preserving at the same time existing output, except that the ticket #2288 (Cyprus: ChromosomeNumbers: formating nameInSource) has been solved

disabling almost obsolte theme override palmweb_2_cdm_descriptionElement_Distribution()

hide empty bibliography

introducing the api hook cdm_feature_node_blocks_alter and removing hook_cdm_feature_node_blocks_alter, this makes theme_cdm_feature_nodes obsolte, reducing speccial code in palmweb theme

more flexible table of content creation, hook_cdm_feature_node_toc_items_alter() no longer needed
