Title: Enable multi-Element Mixin Selectors

Previously, dotLess would require that mixins be selectors with single elements (eg. ".dropdown-menu") since the matching algorithm would try to match only a single element and then drill down into the selector's rules for any additional elements. Bootstrap uses multi-element mixin selectors (eg. ".pull-right > .dropdown"), the drilling down should only be done if the selector does not already fully match the specified selector. I've added a unit test to illustrate the fix, the existing unit tests all still pass. The comments on pull request #323 refer to this issue.
