This update adds the original 2009 release of Inter-Galactic Jewel Thieves.
I completely forgot that I had made significant changes to it sometime in 2017.
It's likely of interest to almost nobody, and if you're on Mac or Linux, it's even less
interesting because the game is Windows-only.
I also added the original 2013 release of Cactus Block 2013. This is also Windows-only.
I thought I had lost it and only had an updated version, but I found it.
This is also likely of interest to almost nobody, but I like including the original
versions of my games in the collection where possible.
Finally, I made a number of small cleanup changes to various game descriptions (fixing typos, adding missing information, slight wording adjustments, etc.)
Initial release.
