4.7.4

[FortyTwoFortyTwo]

Was originally going to be 4.8.0 with bigger features/changes, but releasing current changes now as I likely won't have the time to update further soon.

• Update Chargin Targe and Splendid Screen rarity from common to uncommon
• Remove Demoman's primary ammo gain from kill
• Use attribute names instead of indexs in config
• Use attribute values in config for melee translations
• Use cooldown values in config for translations
• Updated Tank:
  • Increase melee damage by 75%
  • Increase duration it'd take to fully decay health from 35 to 60 seconds
  • Lower max health per player from 500 to 350
  • Increase debris rage cooldown from 5 to 10 seconds
