Second try at changing the "Coder Secrets" into "General Secrets"

Makes the "coder secrets" in secrets panel become general secrets for all admins. Adding myself to admins.txt for test server purposes, in case I ever forget to change it again.

Reasons:
It's very helpful to use the admin log for a quick glance to see who spawned the mateba for the clown, rather than open the serverlog to check.

Plus I see no reason why it should be restricted to coders, considering it's not really at all able to affect the game by admins seeing it.

First PR died due to me forgetting to switch branches before pulling cheridan's changeling stuff. Woops.
