Suggestion: Sync up calendar in the welcome repo .Rmd file with the calendar stored here

[edrogers]

The welcome repo has a welcome.Rmd file that concludes with a calendar of upcoming events. But this repo has its own list of calendar events which can easily get out sync.

I suggest that we consider automatically sync'ing these up somehow. Perhaps Travis could call a script to parse the lektor files for dates, names, and topics, which could then be used to publish a new .Rmd?
