Weights the likelihood of command positions by your age.

For most head positions, a good age is between 25 and 60, with ages towards the middle of that being even better. 25 because I figure for stuff like research, engineer etc. they'll want someone with fresh knowledge. Captain's best age starts at 35 though, due to that being an "old geezer job".

Psychic villain gear.
Changes to increase readability



Specifically formatting the messages a bit differently by putting
them onto multiple lines. They line up properly inside of dream
maker, making them /much/ more readable. This format would be preferable
for new additions into this file.
This just fixes a small typo in build mode.



Specifically, the throw and select buttons were 'switched'
in some instructions. This quickly fixes that!

Fixes a spriting issue



Specifically, the sprite for laying down with clean tajaran
cut didn't have the correct icon_state name. I changed it
to the correct one.

Special Operations crate.
Fixes an issue in grammar!

Specifically, the way that it was coded made it so that the word
the would appear twice. There... really wasn't a way to fix that
in a way that would effect a lot more things, that I could find.
As a result, I simply reworded it so that it can work with or without
the word, 'the'.

Added the ability to give traitors all objectives.



Specifically, admins were unable to give players, traitors,
that is, the objective to brig/maim someone. This gives them
the ability view the traitor panel.
Fix of breacher chasis to keep anyone but Ughanti from wearing it.
Fix of gun suicide - lethal is lethal, nonlethal just hurts like a mother.

Response Team still isn't ticked on. Dunno if it's ready. Re-re-uncommented.
Removes a few typos from channel names


The literal only two instance of gazette in the code.
This should fix it entirely.

fixes #3006
Adds Uranium Capability to Circuit Imprinters


Well, looking over the RUST circuits... They required uranium
which we didn't even have implemented in the code to work with
circuit imprinters. I considered simply changing them to use
a different resource, but it honestly makes more sense to improve
the current code to have it more versatile-- To this end, I've made
circuit imprinters capable of using uranium.

As a further note...
