Tweaked a few bonuses

v1.4 Buildings Update

I wanted to accomplish two objectives with this update (in addition to more flavour buildings):
1. To pivot Yi Ti from a jungle-themed civilization to a more infantry-based civilization; and
2. To move away from slavery laws being enacted in Yi Ti as slavery was not common in East Asia.

This poses some challenges because the files that deal with Yi Ti on these two points also deal with other buildings/laws, and so changes to these files may cause compatibility issues with other mods that change the same things. What I have done here is a compromise solution:
1. I added new buildings that remove war elephants from Yi Tish levies and add tax income instead; and
2. I added another set of buildings that provides powerful bonuses to light infantry, BUT requires that you both have slavery made illegal and that you have constructed the buildings that remove war elephants.

In addition to unique castles in the capitals of every kingdom, this update adds:
- One additional level to fort level defenses ("Advanced Fortifications") that provides powerful bonuses but is in turn very expensive and only buildable in the Yi Ti Region (Note: the geographical region of Yi Ti, not just anywhere with Yi Tish culture)
- Two levels to war elephant pens ("Exotic Animal Trader", "Exotic Goods Market") that remove war elephant levies and add tax income
- Four levels of a new line of archer-boosting buildings ("Crossbow Maker", etc.)
- Four levels of a new building line ("Bomb Maker", "Fire Lance Workshop", etc.), themed around early gunpowder troops/weapons. These late-game buildings provide very powerful bonuses to light infantry as to make Yi Ti armies highly infantry-centred and very threatening in the skirmish stage, but in return are very costly, require that slavery be outlawed, and that no slave camps exist in the holding's county

Let me know in the comments section if you find any bugs or have any feedback.
