List priorities with Owners' names, not avatar pics

[cassiemc]

Some people's avatars are not obvious. @edrushka, for instance: https://github.com/edrushka

I think the owners should be listed by Github name in addition to or instead of their photo.

+1 I suppose I'll get used to peoples' Github handles in time, but for now, it's hard for me to remember that Andrew = Thisandagain. And it will be worse in cases where the Github handle is not the same as IRC handle. Let's keep in mind contributors and future new employees, as we figure this out - try to make things easier for them :)

As long as we do names + pix (& I'd suggest handles as well), that makes sense. The pictures help avoid wall-of-text, the handles are for better or worse going to need to be learned over time, and the names are a good onboard.
