Update to CSSComb 4.0

[1337LutZ]

Since this plugin has not been updated for a while I was wondering if there will be a version 4.0 support?

Right now I can't seem to add new lines after each ruleset with version 3.0.

.a{
  color:red
}

.b{
  color:blue
}

will comb to:

.a{
  color:red
}
.b{
  color:blue
}

If I'm doing something wrong please let me know.

@1337LutZ This sublime package now uses CSScomb 4.2.0. Feel free to reinstall.
