Rename top-level config element

[pgr0ss]

Right now, the top level config element is called devs. We should rename it to brainiac or something app specific.

This was a feature to allow multiple programs to be loaded. You could then hit a URL, ie /devs and only the plugins under devs would be shown.

I removed part of this feature when I upgraded lamina, because I thought named channels were removed. Turns out they weren't and I should be able to add it back
