detect mixing native CSS selectors with non-native jQuery selectors #3

E.g. $('.class:checkbox'); is much better expressed as $('.class').filter(':checkbox'); as this allows as much of the query as possible to be executed by browser-native functionality.

To achieve the best performance when using these selectors, first select some elements using a pure CSS selector, then use .filter().

It would make sense to throw a "PERFORMANCE" reason in this and related errors.
