Han barracks/ stable champions tech

[Langbart]

[26632] and [26633] have added two technologies that are only available in captured barracks/stables of non-Han civilisations.

issue

The info can not be accessed from the structure tree.

possible solution

The Han are by far the most unique civilisation, they can lose this technology or give it to them normally so it shows up in the structure tree.

If you conquer barracks or stables of another civ, you can train champions there. Must be a bug, it's too OP.

I can't produce one specific unit there.

It was thought to be underpowered to not allow the Han to train their champs from a captured barracks. That's why we went through the trouble of making it so it was possible. Other civs can train their champs from a captured barracks, right? 

[Langbart]

The structure tree is not able to accurately represent your idea. If the assumptions of an underpowered "Han" civilisation are correct, then allow to train champions after you have researched the technology normally.

[wowgetoffyourcellphone]

It's a tech for a special case, not a standard tech researched from a Han building, hence would not show up in structree. (Though, I'd like structree to be extended to include such cases; Delenda Est has such a tech for Philip II called "Hegemon" that is researched from a captured Civic Center)

[Langbart]

ok, if the function works, it can be implemented. At the moment it needs to be reworked.

[Gameplay] Han unit roster restructure and other balancing adjustments

After feedback on the first RC's : ​https://wildfiregames.com/forum/topic/83323-balancing-the-han/
This version of the roster seems to have a minimal concensus.
This removes some units from the very big roster of the Han, restructures it and changes the cavalry crossbow champion for an infantry one due to histrorical issues.
It furthermore reverts the changes to the champion infantry crossbow template introduced in rP26469 as that nerf wasn't necesarry.
This means that the Han and the Macedonians now have a champion crossbow unit with the same stats.

Also:

Fixes #6560 by only keeping the "academy" templates, so that the Han can now only train champions from the academy. Therefore, this reverts parts of rP26632 and all of rP26633.
