Jitter fixes, scaling changes, hotfixes

Features:

• Health Bar for level 4+ giants
• Ragdoll hit strength scales with size

Bug fixes:

• Misc stuff that worked in offline mode but not in multiplayer:
  • Leg Day will be applied at lvl 3 as intended (previously only the Meteor ability enabled jumps)
  • Squish and Living Meteor Audio SFX
• Changed the way scaling is applied:
  • fixes glitchy animation when running/jumping (excessive jitter)
  • players should be less likely to get stuck
  • Allows picking up small object with the "crotch cam" (lvl 4+)
  • Player size should no longer go out-of-sync when spawning far away or joining a game in progress
  • Improve hitbox accuracy
    • There is still a dead zone around giant characters where kicks/jabs/squishes are more effective
  • Kick/Jab targeting will be more reliable for giants
  • Squish: effective radius has been reduced (:soon:: knockback effect on players in range)
  • Fixed an issue where giants could crush smaller players by walking

Other Changes:

• Living Meteor sets the user on fire and deals damage (100 per use)
  • Double jumping (Jump + Living meteor) may hurt you
• Jump "ballistic" momentum will only apply to Living Meteor now
• Exposed more variables to config file
