Redesing the layer selection overlay.

[pacesm]

The layer selection overlays has been designed for display of the satellite 2D imagery and it should be adapted to fit better the Swarm use-case. These points should be addressed:

• The layer setting of the satellite "layers" should be shared, i.e., settings such as variable selection or colour-range should be applied to all satellites simultaneously.
• Multiple selected magnetic model layers should not be allowed.
• The settings of the magnetic models should be shared. I.e., when, e.g., inclination is displayed for IGRF12 then after change of the model, e.g., to CHAOS-5 again the inclination with the same colour-range should be displayed.
• Dst and Kp indices are displayed only on the time-slider and they are not data layers. Simple check-box switch (like the one used for Coastlines) would be sufficient. The settings for the indices make no sense.
• Layer (drag&drop) re-ordering does not make sense for the Swarm data.

"Multiple selected magnetic model layers should not be allowed." - Would this imply that it is not possible to look at the difference between two models?

@miktoki: We already removed the automatic-difference calculation from the client (as it was implemented in the prototype) anyway because it was quite confusing.

Note that the model difference calculation still exists on the server but we have to find a less awkward way how to expose it though the WebUI. One of the options is, e.g., selection of the (second) reference mode from the model settings' widget.

Update: All expect but first point seem to be resolved.

The fact that the options are not synchronized for all spacecraft is confusing and setting the same product parameters for individual spacecraft is unintuitive. (E.g., I switch from A to B. Why the hell the globe shows something else than I've just set? Oh crap, I need to set the same again for B!)

Is there actually a case when having settings for different spacecrafts would be preferred?
