* Added Civilopedia entries for each of the units.

* Templar Knight now requires a Shrine instead of a Temple.

I ran into an issue where the Khmers' Prasat wasn't allowing you to buy Templars, and the only way to fix it was either to add an awkward dependency, or change the building requirement. So I went for the latter.

* Adjusted unit Combat Strength and base cost to fit better into the April 2021 patch.
* Templar now also get +5 strength if the Religious unit is adjacent to them. (Same as Conquistador)

* Fixed an issue where using this together with the Support Units tweak would cause the Civic units to lose their icons.

* Changed the model used by the Landsknecht Pike & Shot to that of a musketman because for some reason the pike & shot model kept glitching out and turning invisible, and I can't figure out why.
