Added jsHint to enforce coding standards.

I'm referring to anything in between methods.  If we're talking only about the line I put this comment on, it's just that this is where you start the chaining, by removing the variable declaration and the semicolon.

And really it's not like I throw a lot of non-controller methods in between controllers.  But I appreciate the freedom that them all being independent entities allows me nonetheless.  A lot of the examples in the Angular documentation always seem difficult to parse due to being endlessly chained, I think it's easier to parse visually when they sit alone.  It's not like there's any significant difference in amount of code or lines written either way.
