UI Scaling for HiDPI

[tuomount]

Let's make issue for UI Scaling for HiDPI displays. This has been started already with following Pull Request: #793

There are still some work to do:

• Go through each label render and modify those.
• Add ListSelectionListener for PlanetView to show building information
• Planet number line stroke is too tall when zooming out. This was already in previous version, but color was almost transparent so it wasn't obvious.
• Now Sun labels in starmap are wider and not redraw from right hand side
• Galaxy creation does not fit into boxes with smaller resolution
• Fix SpaceCheckBox nothing is drawn if no text.
• Add scale support for RealmSetupView
• SpaceCheckBox icon is middle of text y-coordinate, not in top of the box.
• Fill and test docs/UI-SCALING-TEST-PLAN.md

I have picked up the Label Renderers and will complete them starting tonight EST.

I changed planet label color. It is now transparent when zoom level is normal or out. I am still able to read planet number. What I don't like is that planet number can mess up possible ship on orbit. I also tried drawing fleet after text, but then I am not able to see what planet is which planet. I also noticed when zoomed in and planet label is not transparent small ships can be also behind the label.

I am not sure how to do this correctly. @dev-ricks was there a reason why did you change label color green for regular planets? Was it for easier to read? Previously color was transparent and I did not notice that label text was so big for zoomed out map. It basically covered whole planet and near by tiles.

@dev-ricks How it is going with those label renders?
