Move SOmap_auto legend

[Maschette]

it would be good to have the legend default for SOmap_auto on the left side of the plot, or add the functionality to pick it.

Can you give an example of a legend with SOmap_auto? I think these will only come from plotting a raster (via SOplot)?

[Maschette]

I am pretty sure when I first put this issue up SOmap_auto still printed the bathymetry legend by default but it is when you use SOmap::SOmap_auto(bathyleg=TRUE) which has also highlighted to me something is not right....

2075f13. Legends with autoplot are horribly problematic. I am wondering if we should not abandon aspectplot.default to set the plot up when there is a legend, and just let raster handle it. It won't necessarily make maximum use of space, but it much less prone to catastrophic layout failures. Needs discussion.
