Small release: Seasonal Marker

[hello_robotto]

While I was taking screenshots and testing and such to fill out the wiki articles on metarooms, it occurred to me that a small UI element that simply tells you the in-game time would be useful, instead of having to rely on things like the Dustdevil Grendel calendar or the Garden Gnome, or pinging the console. A brief search didn't turn up anything (sorry if I missed yours), so I made one! I'm having a real frustrating time in other languages - I made and tested this while installing and re-installing things to try and get an R package to recognize CUDA's existence, and I am still not there - so it was nice to go back to CAOS and code something simple.

The marker is up on CCaves here and changes color for each time period, number for each day in the season, and shape for each season in the year. It injects by default in the upper-left under the creature UI, but can be moved wherever you like. Not for use on the off chance you've been messing around with your GAME seasonal variables :p

While I was at it, I also added a small section on formatting agent help catalogue files to the wiki page, because although I ended up not using it, I swore there was some way to color text in them, but couldn't find it anywhere. Or how to do newlines, for that matter. Now it's on the wiki for next time I forget easy reference.
