Version 0.9.4.21 is Live! -- Starmap and Interstellar Trade update

This new update brings a complete overhaul to interplanetary trade:

* You can now redirect trade ships to new planets if you decide they'd be more efficient there. Or if, you know, unexpected situations arise that make a planet need a little more help than usual.

* Trade routes can now be configured to carry as many types of resources as you like -- but there's still an overall limit on how much cargo a ship can carry.

* The Galactic Map looks six orders of magnitude better than it did before. Many thanks to Freya Holmer's "Shapes" Tool for making this possible. =)

Also, a number of bugs are fixed:

* The screen won't zoom in and out wildly if you use the mouse wheel to scroll thru a scrollable window.

* The number of colonists on a colonization mission is no longer accidentally clamped at 5.

* I've added better error logging for any bugs that happen with regards to save files, so those should be easier for me to track down in the future.

* Oh, and I guess this isn't a bug per se, but I've made some tweaks to improve the clarity of the UI.

Next up, I'm planning on looking into better procedural generation of planets. I think there's a lot I can do there to add more detail without losing the 'low poly' look. Expect an update on that early in 2022!

Thanks for Playing!
