Friendly suggestions

Ok, so I saw @datachomp open this project up.  I took a look, and I thought I'd throw in a few suggestions.  

I did this while watching tv, so don't trust everything... my attention was spread out.  

This line of code will not run now, with my change here:

https://github.com/nerdbeers/nerdbeers/pull/22/files#diff-02a5318c3c8a520e68f507723e3e8b3dL14

But it won't run for good reason, it should be pretty easy to change. **cough cough**
