Standardized the type checks across core. isFunction and isArray now use Object.prototype.toString to verify the type, .constructor use was removed in favor of typeof, typeof checks now use ===, undefined checks use === undefined. All of this is outlined in the new style guidelines: http://docs.jquery.com/JQuery_Core_Style_Guidelines#Type_Checks. Fixes bug #3618.
