Info-specific parameters

The classic BYOND statpanel, which contains both stat and verb tabs. This is technically a 3-column grid with a variable number of rows.

Output to a statpanel is done via the stat() and statpanel() procs, during **BROKEN LINK: /atom/proc/stat**.

The same limitations that apply to grid output apply here.

Info controls can now be split so that one displays stats and another handles verbs.
