MCHeli Rework 1.1.0-beta.5

Phase 9 of the road to 1.1.0: the vehicle screen and what goes with it, supply vehicles and
thermal view. Betas are not uploaded to CurseForge, and this one ships the Forge 26.3 jar only.
Worlds from 1.1.0-beta.4 load as before; their vehicles come back with empty slots. Players and
servers need the same version, since the network protocol changed.

Added

• The vehicle screen, on I in any seat (the original's GUI key, R, switches seats here). It has
  three fuel slots that empty fuel cans into the tank while the vehicle stands on something, a
  parachute slot for each ejection seat, and a weapon panel that shows every weapon's rounds and
  reload cost and reloads it from your own items. Closing it after a reload loads every magazine.
• The cargo chest of vehicles with an InventorySize, from the vehicle screen's Cargo button or
  with Shift + right-click on the vehicle from outside. Sizes between rows round up to a whole row.
  What a vehicle carries drops when it is destroyed or packed up.
• Ammunition trucks (AmmoSupplyRange) rearm every vehicle around them that stands on something,
  a tenth of each weapon's maximum every two seconds.
• Repair vehicles: RepairOtherVehicles = range[, value] mends every vehicle in range by value
  hit points a second (10 by default). None of the original vehicles uses it; packs can.
• Thermal view: K now steps from night vision to a white hot thermal view with outlines and back
  to normal. The HUD's cam_mode reads 2 in it, as in the original. The original's vanilla
  "pencil" shader no longer exists, so the filter is our own.

Changed

• Ejection seats need a parachute in the vehicle screen's parachute slots, one per ejection, as in
  the original. Without one the seat stays put and says so. Creative players need none.
• Reloading a weapon from your inventory moved from the N key to the vehicle screen and only works
  on the ground, as in the original. The empty magazine hint on the HUD names the new key.
• The network protocol is now version 8.

Fixed

• A helicopter on the ground no longer tilts with the pilot's mouse; it stays level until it
  lifts off.
