Add more coasters

[crcastle]

One thing that gets non-technical people excited about keg.io is the coaster achievement functionality. Users can earn different coasters (like foursquare badges) based on their drinking activity. For example

Party starter (first drinker of the day)

Early bird (have a beer before noon)

You can see all current ones we've though of here. Some are implemented. Some are placeholders.
https://github.com/dcarney/keg.io/blob/develop/lib/models/coaster.coffee

Please add some more!

Make a pull request that updates coaster.coffee, keg.coffee, and provide a new coaster image. If you only have the skills to do either the coding or the graphics, I'm sure someone else can help you out!

Other ideas:

• Beer Aficionado: A person who has poured at least one beer from every keg. This should be awarded after someone has poured a beer from the 5th consecutive keg. It should be taken away if they pour a beer and have skipped a keg.
• Power User: Awarded when someone pours a beer each day for 5 consecutive days.
