implemented toString() for MultiValuedDeclaration#PropertyAndLayer
Fixed the issue in finding type III duplication
(A virtual shorthand declaration should not be compared to another
virtual shorhtand)
Changed CSSAnalyser calss so it also uses Less parser
Handled the case when values for a function could not be parsed
This happens mostly when we have IE-style filters
Added number of dependencies to the toString() of CSSDependencyList
Moved the batch duplication refactoring logic to RefactorDuplications
