  - Added a plugins option that allows specifying an array of visitors run on the less AST
  - fixed issue when adding colours, taking the alpha over 1 and breaking when used in colour functions
  - when adding together 2 colours with non zero alpha, the alpha will now be combined rather than added
+ - the advanced colour functions no longer ignore transparency, they blend that too
  - Added --clean-option and cleancssOptions to allow passing in clean css options
  - Fix possible issue with import reference not bringing in styles (may not be a bugfix, just a code tidy)
