MAJOR Battle Graphcis Update with a lot of graphic improvements and reworks

*horses and camels - broadly reworked horse and camel textures leading to a more immersive horse and camel texture look + added new horse and camel color variants (9 horse color variants, 7 camel color variants). each cultural army and quality tier has it's own custom horse/camel color variant set. each army culture therefore has 3 different horse/camel color sets that are being used for their armies.

*horse cloth and horse armor - many cultures received new horse clothes or horse armor depending on their culture and if i thought it does fit into their culture. horse armor and horse cloth with coat of arms attached to it will usually only be used by T3 cavalry

added coat of arms to some unit clothes - mostly T3 units but also some T2 units

improved bow model with string and arrows with feathers + iron head replacing old model which was only wood

improved spears by adding new iron spearhead

added new big flags with coat of arms attached to them (only being used by T2 and T3 armies)

almost all armies of all cultures received general texture improvements like
- better and more consistent coloring
- better lighting
- better color consistency across unit variants
- better armor shinyness
... by either reworking existing textures or adding some new textures etc. - also included animation bug fixes when necessary. some armies already had good textures and quality, improvements for such armies might be smaller compared to those armies that had worse quality.

some cultural armies also received bigger reworks with more unit variants, completely new textures, and some new 3D models - i will add more and more details and variancy across unit models in future updates. once i am done with making all existing armies look like i want them to look, i will also start to work on new animations

*included update for CK3 version 1.14.* and West Slavic Content Creator Pack DLC

*includes bug fix for making all court artifacts visible again. previously some court artifacts have been invisible. this happened because even though Battle Graphics mod does not modify any court artifacts there is a link between unit gfx and some court artifacts which i didn't know about before ... thanks to James Keenan and monkeman1967 for letting me know about this bug

*included update for CK3 version 1.14.* and Wandering Nobles DLC (also compatible with CK3 1.13.*)
