Use same colors in map view/table view in the geometry comparison tool

[gioman]

In map view it would be good to use the same bright green/red used in table view. I also wonder if in table view we should not use the same wording used in the "merge conflicts" tools, so local/remote instead of "base geometry/compare geometry".

I have changed the wording. If you want to change the styles, you can just modify the files referenced here (all in the 'resources' folder)
