clean up git_hub_bub interface
Authenticate every github call

Problem: Github is rate limiting Code Triage result resulting in repos with no issues and therefore plenty of users with no emails :(

Solution: Add a random github user token to EVERY CALL. Github gives you more calls when you're using a token. 

Do i love it: no. Will it work: probably.

Group triage emails together 

This branch adds a new UserMailer method that accepts multiple issues and groups them into one single email. So if a user subscribes to 20 emails, they will get 1 email a day with 20 issues instead of 20 issues a day with 1 issue.

For now the older subscription notification code will not run and all users will receive a "digest" email once a day instead. In the future it would be trivial to add a flag to user accounts to allow them to opt to receive multiple emails instead.
