Heads up: Tilt lazy loading of org-ruby is being deprecated

[jeremyevans]

I wanted to let you know that I've deprecated the lazy loading of org-ruby by default in tilt. See jeremyevans/tilt@98a75d3. To allow for a transition period, the deprecated support will remain until tilt 3 is released (no ETA yet, and unlikely to be this year). I recommend that you adjust your documentation to explain to users that org-ruby should be required manually before using the tilt integration.
