CLIMATE-152 - Adjust dataset add/remove buttons
CLIMATE-152 - Adjust dataset add/remove buttons

- Place the dataset add and remove buttons into separate divs. This
  prevents the divs from stacking when the window is resized below a
  certain threshold. Now the buttons remain side-by-side for (nearly)
  all sizes.
