Adds reducing non-adjacent selectors.

* Removes repeated properties in same selectors which are not next to each other.
* E.g. '.one{color:red;margin:0}.two{color:#fff}.one{margin:1px}' will become '.one{color:red}.two{color:#fff}.one{margin:1px}' because margin is repeated.

 * Changes behavior of `--keep-line-breaks`/`keepBreaks` option to keep breaks after trailing braces only.
 * Makes all multiple selectors ordered alphabetically (aids merging).
 * Adds property overriding so more coarse properties override more granular ones.
