Changes to "Coder Secrets" in the "Secrets" panel

Edited the coder secrets to be available to all admins, as they are useful in general and can't harm anything. The admin log especially is very useful, allowing at a quick glance to see who did what, rather than open the server log.

Also added myself to admins.txt because it's annoying starting up a test server only to see I forgot to make myself an admin.

I did test this. It puts the Coder Secrets at the top of the secrets panel now, right under the header, meaning it's viewable immediately upon opening.
