Indentations do not match. jshint says following:
```
line 7   col 24  Strings must use singlequote.
  line 12  col 28  Strings must use singlequote.
  line 21  col 9   Expected '}' to have an indentation at 11 instead at 9.
  line 22  col 5   Expected '}' to have an indentation at 7 instead at 5.
  line 22  col 6   Missing semicolon.
  line 26  col 4   Expected '$scope' to have an indentation at 5 instead at 4.
  line 27  col 8   Expected '$http' to have an indentation at 9 instead at 8.
  line 28  col 12  Expected 'loadFriends' to have an indentation at 13 instead at 12.
  line 29  col 8   Expected '}' to have an indentation at 11 instead at 8.
  line 30  col 4   Expected '}' to have an indentation at 7 instead at 4.
  line 30  col 5   Missing semicolon.
  line 4   col 64  'Auth' is defined but never used.
