Github in irc announcer

Poll every hour for new shit on github by our members:

e.g.: curl -H "Accept: application/vnd.github.v3+json" https://api.github.com/users/folkertvanheusden/events

this returns a list of events. each has an 'id'. keep track for each member the last id retrieved.

if an id is newer, push the url etc to irc

Rest sample output:
