- removed redundant local variable "name" from activateFunctionalities(), replacing occurrences with global_currentInputUnitName (equal to "name" after unit is clicked)
! fixed minor bug: unit names are now displayed in menu instead of "undefined"

# un-refactored (in parts) overall project structure: removed (yet) hardly used modalWindows files, added controllers files
# updated (as of yet unsued) contextInfoModel
# put several pieces of functionality in their (for now) right-er places, like e.g. addUnitToScenarioModel(), addUnitToMenu(), ...
- removed redundant replaceMarker2()
+ translated enums in contextTab filler

# refactored functionaliies.js into reloadController.js (comparison: function preserved)
# in reloadController.js: changed jQuery.ready into jsPlumb.ready due to delayed inst initialization
# simplified metaIcon choice and adding
# moved more code from general (tabs, modalWindows) to more specific files (metadataTabView, createScenarioModalWindowView, ...)
+ added propertyTab.js
- removed several unnecessary files from MVC scaffold

# further refactoring toward MVC
