CSS editor improvements

  1. Possibility to insert rules from clipboard
  2. Possibility to create nested rules.

Thank you for the suggestions!

  1. This is already possible - you can paste CSS in the editor when you edit CSS selectors, properties or values. The CSS will get parsed and inserted.
  2. We wan't to keep the CSS editor simple so we've taken the decision not to support nested rules like keyframe animations, if this is what your suggestion is. But we will have support for SASS soon, which will enable you to write CSS code in the editor as well.
