Spiritus Astrum [P0-B13]: p1533: Towards Early Access

I have made some changes and improvements to the new UI camera system, in order to fix some bugs that I found.

I also discovered a long standing issue with the ground cover rendering when on planets. Under certain circumstances the grass renderer was being applied twice, breaking grass exclusion, and no doubt causing additional framerate hits.

This has now been fixed too.

I have just a few major objectives left before I can enter early access.

The game is still in a relatively unfinished state, but I can leave a lot of the final work until after the EA phase.

The only major goals left are to add more artwork to the first and third campaigns, and add and test a checkpoint system.

Then the only goals left are lots of testing, more and better artwork, and more story improvements, etc, etc.

I have started work on the remaining artwork now.
