Rearm - Add pylon position check

[ampersand38]

When merged this pull request will:

• Adds a check to see if the pylon ammo being held by the player is in the correct position and alignment near the pylon
• Adds checkbox setting to enable the check, default off

• Check will only activate if all conditions are met:
  • the current ammo is a pylon magazine and has a dummy model specified, not the default box
  • the setting is enabled
  • the Rearm Amount is not "Entire Vehicle", but one of "Entire Magazine" or "Based on Caliber"
• Shows ace-style hints if ammo is too far or misaligned. Should the limits be configurable in settings?

- Adds interaction to flip the ammo object being held for easy of aligning

• Adds dummy ammo objects for more base game pylon ammo types
