Improved Jumping

I was annoyed by the skewed jumping trajectory in FNV especially noticeable while sprinting, and decided to fix it with several more features along the way.

Enabled by default:

• The trajectory follows a proper parabola.
• Sprint enables longer and higher jumps.
• Jumping consumes AP, jumping while sprinting consumes more. Higher strength - lower AP cost.
• Increased vertical jumping speed (reduces floating feel).
• Height scales with running speed, agility, and strength (AGL/STR are enabled only in exteriors due to low ceilings in many locations).

Disabled by default due to being a matter of taste:

• Committed heading, configurable level of steering mid-air.
• Post-jump inertia (makes a step or two after landing, depending on speed).
• Weapon out distance penalty.

All parameters are configurable/toggleable in ImprovedJumping.ini.

Requires xNVSE.
Compatible with Enhanced Movement and Just Vanilla Sprint.
