title: change line height in sublime text default theme after changing the font-size
body: <p>I found this link on stackoverflow: <a href="https://stackoverflow.com/questions/13781833/sublime-text-2-how-to-change-the-font-size-of-the-file-sidebar">Sublime Text 2 how to change the font size of the file sidebar?</a></p>
  
  <p>I followed the directions and changed the font size, but now the font is too big with too small of a line height, so it looks stacked on top of each other and cut off, without any room to breathe.</p>
  
  <p>Is there a json label that I can use to change the line height/padding? Thanks.</p>
