Changes some messages to make more sense
Fixes entropy calculation

Fixed the entropy calculation so that it is easier to remove gas from a
hot gas mix, not harder. Added comments explaining the entropy
calculation. Also returns pump and filter efficiency to previous values.
Merge remote-tracking branch 'upstream/dev' into AtmosList. Atmospherics Control Console no longer sorts the machines list, as this is now done elsewhere.
Remote air alarm control for the isolation cells now available on the outpost.
Merge remote-tracking branch 'upstream/dev' into StatusDisplay. Moved code in New() into initialize().
Quick fix for engine core flow imbalance

A more thorough fix should probably involve providing a way for players
to control the flow rate.

Also tweaks emitters and allows collectors to be read using a multitool.
Removed debug statements
Allows power to be read by examining the collectors
Fixes #6118
Adds ChessPiece's species hardsuit sprites

Adds ChessPiece's onmob and inventory sprites for unathi and skrell hardsuits, as well as nicer tajaran hardsuit inventory sprites to replace the current placeholder ones. Adds hardsuit spritesheet entries for unathi (skrell will come later).
