plotting scheme restructured: the same widgets are used for plotting the overview and the station plots, the plotting method has been moved to the widget side which makes more sense than having it on the data side;

new functions in utils module: prepTimeAxis returns a proper time axis array for a given start time and an obspy trace; getGlobalTimes returns the minimum start time and the maximum end time (edges) of a given obspy stream object
