V11
-------------------

Added compatability with Gazebo's City State Diplomacy mod (CSD) - version 26.

In order to achieve this, a few changes are made to CSD content when both mods are running together:

- CSD's Crystal Palace wonder and changes to World's Fair project will not appear (to avoid conflicts with the identically named Crystal Palace wonder in C&I), Worlds Fair will function as in the unmodded game.
- CSD buildings/resolutions/units that would have unlocked during the Industrial era or later instead unlock at appropriate Steam and Gaslamp era techs.

V.14
---------------------
Now using relative rather than absolute values to place eras and technologies, to allow compatability with other era mods. Big thanks to whoward69 for his tutorial.

V.28

Using SQL triggers to listen for UUs added by other mods, without the need for individual references (there are a lot of fine mod civs out there).
Civ-Unique variants of units from any and all other mods should now unlock at the appropriate Steam/Gaslamp era tech and upgrade into the appropriate Steam/Gaslamp era unit.
