Generated scss now contains some extra newlines

Inserting some newlines to make the beautified code a bit more readable. Right now there's only two rules where an extra newline is inserted: 
1) At the end of } (unless it's at the start of a line, sass-convert seems to separate top selectors with newline already)
2) If a lines ends with ; (indicating a property has been defined) and the next line contains { (indicating the start of a selector), then an extra newline is inserted between the two lines.
