[MoM] Nether Attunement affects psionic calorie usage

Summary

Mods "[MoM] Nether Attunement affects psionic calorie usage"

Purpose of change

Thought about doing this for a while but the motivation behind the other PR (the strategy of sitting on buffs at high Nether Attunement, or of just activating Torrential Channeling to get a bonus to your buffs and not actually channeling any powers) brought it forward in my mind.

Describe the solution

Multiply calorie expenditure from psionics by your Nether Attunement adjustment. At no Attunement this is a buff (calorie expenditures will be 75% of previous values), and it's not significantly higher at low Nether Attunement levels, but sitting with Torrential Channeling on for long periods of time will raise it by 50%, and going even higher will get into 2x-4x previous calorie expenditures.

This also means that contemplating already-known powers becomes more taxing the longer you do it at a stretch as your Nether Attunement rises.

Describe alternatives you've considered

Testing

Used Earthshaker at various levels of Nether Attunement and noted calorie cost.

Also, repeated Earthshaker usage destroyed the floor and dumped me into the basement of the evac shelter, which was pretty cool.

Additional context

Torrential Channeling might need further adjustments--the best way to do it and Extended Channeling (if it weren't a UX nightmare) would be a decision you made when you channeled a power, rather than a modifier trait you toggled on and off, but even if I wanted to do that and it would be a good idea, I don't think it's actually possible without massive (undesired) C++ changes to how power usage works.

Well that's just bad as heck.
