Complete UI overhaul
Fixed MapVisualization
world map and continent map working
added mapModes & corrected list loading

-Needed to take onClick handler into ContinentMap because of to few
informations

-corrected empty line in list (wrong start index in for loop)

-set productList enabeled if data is loaded, fixes bug of selecting a
position while the list is not filled. BUT now its changable befor
Continent is selected...
Implemented static listbox for product selection
to prevent unnecessary reloads of product names
