Important: The last release that appears in the project page, is not really the last one. See this release instead. Changes:
* Added semicolon to the start, for safe file concatenation.
* Minor changes for perfomance.
* Made many changes tp $.rule.fn.filter
o The filtering function used to get element & index as arguments instead of element as 'this' and index as 1st argument.
o String filters are no longer turned into regex, now they are compared (case insensitive) to each (splitted by comma) selector...
