Bugfix (3778) Power cells in exosuits have the same amount of power as a highcap cell

Issue:  Mechs are created/spawned with a high-capaciter cell that is named "Power cell" and confuses some of the less bright roboticists and their beards.

Solution:  Shave the roboticist, and also renamed the cell that spawns to properly reflect it's higher capacity.

Resolves #3778
