completed by: kharvd
mentors: Torsten Rahn, Earthwings
The task "Favorite weather stations in Marble" has introduced concepts that can be generalized for all Online Plugins. This task is about making these concepts more generic by putting them into the AbstractDataPlugin. Also a cleanup/refactoring of the Online Service Plugin classes should be considered (in communication with the Marble Developers).
