0.9.77b BM-13 "Katyusha" and Artillery-Related Changes!

[h2]🚀 0.9.77b Update Announcement[/h2]

Hey Commanders! Here comes the 0.9.77b update!
Rocket vehicle, field guns, skill changes, and tons of fixes and tweaks. Let's take a look!

[h3]🚜 New Vehicle Arrives![/h3]

• "BM-13 Katyusha" is here!
  A 132 mm multiple rocket launcher, affectionately known by soldiers as "Katyusha".
  She can summon a BA-10 scout car to designate artillery strike coordinates.
  Yeah, Katyusha has been awaiting the indirect fire system for over two years, and now it's finally ready to go!
  

[h3]💥 Artillery-Related Changes[/h3]

• Added 6 new field artillerys. Enemy artillery positions will now primarily consist of fixed emplacements.
  
• BA-10 gained the Artillery Strike Call skill and now starts battles with one Rank1 field gun ally.
  
• SPG Advanced Difficulty Level 5 effect has been changed to: Enemy bunker count +30%.
  
• Fixed a bug where the explosion debuff in SPG Advanced difficulty could reduce enemy stats below zero,
  sometimes even making enemy tank destroyers grow turret out of sheer rage.
  
• SPGs will no longer automatically adjust gun elevation when equipped with non-HE and non-rocket weapons.
  
• When SPGs perform artillery strikes, shells will now correctly hit vehicles instead of passing straight through them.
  

[h3]✨ Zina Skill Adjustments[/h3]

• New skill "O Great Katyusha!":
  Ally rocket weapon fire rate and reload speed +50% (also applies to the player).
  
• "Sharing is Caring" skill effect changed to:
  All hull upgrades you choose afterward will also apply to allies.
  
• "Shell Shock" has been renamed to "Ignite":
  Effect changed to Ally rocket weapons Damage +5 (also applies to the player).
  
• Added Zina's Live illustration!
  

[h3]⚙️ Other Optimizations and Fixes[/h3]

• Optimized textures. The lowest graphics setting now looks more like a PS1-era game, but performance has also improved.
  
• Fixed an issue where some support vehicles no longer spawned with friendly units.
  
• Fixed a display bug where scouting skills appeared to massively reduce enemy armor.
  
• Fixed an issue where captured enemies were still hunted down by resentful friendly units.
  
• Fixed a bug where the Commissar's starting event could reappear later as a random event.
  
• Fixed several SPG decoration positioning issues.
  
• Fixed multiple Karl-related bugs.
  
• Updated Karl's sound effects.
  
• Added a more robust save protection system.
