* Fix and test for bug #1457 (Uncaught SyntaxError: Regular expression too large)
- see test case which is extracted from a real world css file; the selector regex was able to traverse the curly brace as when looking for quotes, it wasn't taking into account that the start quote could be escaped
* Apply formatting changes
* Create fair-ducks-clean.md
* Fix @import regex bit which was stopping consumption in the middle of a url - need to consume quotes.
Thanks dave.kindel@pendo.io for reporting and isolating this case
