csscss splits shorthand rules into separate rules

[timeinfeldt]

Hi,

when parsing:

border: 1px solid $grey5;

Csscss throws a notice like:

... share x rules
  - border-bottom: 1px solid #cccccc
  - border-left-style: solid
  - border-left-width: 1px
  - border-right-style: solid
  - border-right-width: 1px
  - border-top-style: solid
  - border-top-width: 1px

This happens for .css and .scss files.
