Show which operations comply to computational region

[wenzeslaus]

The general rule is that everything follows computational region, however in GUI it is actually not the case and it is not when novice user expects. My suggestion is to add a notice to all places in GUI saying how computational region applies.

For module dialogs, I think all dialogs can just have same general note. This may be confusing for vectors and general, so we may alter the message for those. In GUI, 3D uses resolution. Many things like r.report, r.univar, r.colors, histograms have unclear relation to region in GUI.

I have a simple patch for the module dialogs, but some discussion may be needed. Line like this may be in couple of other places so the compromise is between additional information for greater understanding and more clutter in GUI.
