Move DB updates to cron

[osowskit]

The app shouldn't tie DB updates to IFTTT calls. The data updates should be on a local schedule.

Check DB if requested venue/beer/user already has record
If so, update: else add new

cron should run every 30-60 minutes for each trigger

• update user wishlist once per [week|day|API call]
• update venue beer activity once per [week|day|API call]
