No gameplay changes.

Fixed a text description error on the Opera of Light wonder.

Update 8/18/2020

Added lua code to allow AI units to obtain their own Melmarks (since AI almost never purchases items).
Removed Weapon Triangle support for Bomber and Fighter Mirage units because it was causing a bug where they would receive ground promotions instead of air promotions.
Buffed the Blackscale Rider Mirage (bomber unit) from Ranged CS 39 to 42.
Buffed the Idolasphere Gate national wonder from providing 3 Performa to 5 Performa and made it improve military production by 10%.
Nerfed the Idol Promotion tech so that Vending Machines receive only 1 additional culture at that tech instead of 2.
Buffed the Vocaloid Technology tech so that Vending Machines now receive an additional 3 culture at that tech.
Moved the Carabia Jewelry world wonder from the Idol Promotion tech to the Concert Logistics tech.
Minor text error fixes.

Update 7/7/2020
Fixed a bug that was sometimes forcing Mirage Medeus to embark on water. Mirage Medeus should now always fly over water or land. (This was done by changing him to DOMAIN_SEA, so internally he is treated as a flying boat instead of a flying land unit)
