Another small patch today, minor cleanup and final prep for the next workshop release.

- Colony age will no longer appear when a colony has 0 pops. This fixes an issue where you could see the colony age GUI during the colonization process (where it was vaguely weirdly looking because it wasn't actually counting yet.)
- More modded planet classes will now display a dynamic key (e.g specify moon and current weather) without needing a patch
- Fixed a sneaky double space in dynamic planet class keys (that didn't have weather).
- Other back-end bits for "Wp's New Worlds"

Fairly large update to backend stuff, mostly revolving around mod compatibility and preparing for "Wp's New Worlds" releasing in a few days.

If all went well this is now much more compatible with ZoFE and their new planet classes will display the nice art!

A small-ish update today, just some small bugs and tweaks being fixed:
- More changes to fallen empire colony age buttons
- "Colonizing" GUI area has been moved to a more central position. Missed this one for launch, whoops!
- Added an art mask file for people to use when adding their own art
- Added compatibility support for modded ringworlds - they no longer use fallback art!
- Fixed a bug where new colonies weren't having their years counted.

- Added space for even more districts (someone reported wanting space for over 20!)
- Added general scripted trigger to show the mod is active, in case people want to use it.
- Slight tweak to fallen empire colony age view, when they expand or collect systems they will now no longer instantly be "primordial" colonies.
- Slight tweak to ancient colony ages ( turned > into >=.)
- Tweaked version number (added the new "V" paradox wants.)

Initial release!
