Add grenade trajectory, RPG armour priority, empty chargers, mega gravity gun

- Projectiles gets a "Grenade trajectory" toggle. While a frag grenade is
  held, simulate the weapon_frag throw (1200 u/s forward + 120 z, player
  velocity, gravity 600) and trace each step with a new
  trace_solid_segment(); reflect on impact, stop on a slow upward-normal hit,
  and draw the path, landing cross and a 300-unit blast ring. Verified on :99
  (arcs, bounces off the tunnel wall, lands).
- With the RPG equipped, armoured NPCs (striders, gunships, dropships,
  hunter-choppers) sort before normal enemies during target acquisition.
  Added helicopter/chopper to the ARMORED model list.
- Empty health/suit chargers are hidden: read m_iJuice from the server
  datamap (0 = depleted, -1 = unreadable/fail open).
- The citadel supercharged gravity gun (d3_citadel_03, d3_citadel_04,
  d3_breen_01 via IVEngineClient::GetLevelName) is treated as a normal
  weapon, so the melee aimbot no longer restricts it to VULNERABLE NPCs.
