Removing 'archived' widgets and jobs (that's what version control is for anyway).
Dashing now saves the last events in a file so that they can be re-read when the server starts. Ignore this file because it doesn't belong in VCS.
Refactoring jobs...

- Split carbometrics job into separate jobs, one (roughly) for each widget
- Rename jobs (or widgets) to match one another
- Randomize the start time for each job
- Handle the case where we don't get any posts data from carbometrics
