Tidying some descriptions and masses of weapons that were juggled about. Marking as v1 as I think it should be stable now

Added a billhook and 1hAxe to Cimmerian

Added a 1H stabby sword to Cimmerian

Balance pass. All weapons are balanced v star metal as a reference. Rather than drop damage for substances like bronze, I have reduced armour pen and durability instead. Bronze can get a very good edge, it just doesn't keep it excellently, and damaged quickly under abuse.
Corrected XP values for crafting and repair. Repair requirements set to 40% of the first 3 ingredients, rounded down.

Added a Han Dynasty Sha, aka, spear with a long blade.

Re-organizing Feats and feat tree, tiny bit of texture work to de-shiney a few objects

Adding feats and recipes. Still a bit unsure how to use the nearly completely redundant feat tree table, so leaving sorting that out until I confirm feats and recipes

Add remaining weapons, items only.

Very test - adding Khitai set of swords based on copy paste rows of item table
Rescale Khitan swords, adjust hand position, tweak tables and attempt to add icons
Recompile for icon silliness

Add admin only Aquillonian Arming Sword, and correct UV unwrap on Viking Shield (I changed it for the texturing and never reloaded in Unity)
