Functional Jetpack Nerfing

A rework of the "Jetpack Nerfing" MOD.

This mod modify the "Characters.sbc" files and change the following definitions from the "Default Astronaut":

ForceMagnitude to 540 from 3200 SlowdownFactor to 1 from 5 MinPowerConsumption to 0.0000011111111111111111111111111111 from 0.000000001 MaxPowerConsumption to 0.0006 from 0.0001 ConsumptionFactorPerG to 135 from 250 EffectivenessAtMinInfluence to 1 from 0.67 EffectivenessAtMaxInfluence to 0 from 1

This makes the jetpack useless on planetary bodies with an atmosphere or with moderate gravity but still functional on non atmospheric moons up to 0.25g. They are still very useful in space but slower. No longer can you rely on them as your main mean of transportation!

This won't change jetpack properties from custom skin mods, just for the default male and female astronaut.

Note that 0.25g was set as the maximum jetpack operating gravity force: Thrusting upward while pushing slightly forward should be enough to allow hovering under these conditions.

More numbers:

[i]Using only the suit internal H2 reserve tank (i.e. no H2 refill tank in inventory):

0g operation at full throttle, ~5 minutes of autonomy 0.25g static hovering operation, ~90 seconds of autonomy 0.25g operation at full throttle, ~60 seconds of autonomy

On planetary bodies with no atmosphere:

Operation below 0.25g, not tested but should scale accordingly. Operation above 0.25g, hovering not possible, forward movement on ground possible. Autonomy scaled accordingly.

On planetary bodies with an atmosphere, operation is not possible.

Zero-g acceleration performance: 0m/s to 110m/s in ~21 seconds. Same for deceleration.

Note: 0.25g is SE gravity force on the moon.[/i]
