Subject: [PATCH] Modified metricKeys to handle multiple graphite sources.

This wasn't all too hard to change, I mostly changed the
single http get to multiple http gets, one for each data
source of type graphite.

It's still not a good idea to call this on the web
frontend, since the whole thing was working for about
20 - 30 minutes when I clicked it, so I'm not
committing my changes to settings.js or the view itself.
