Title: Fixes #8545

Example in ticket actually illustrated two leaks, in two functions - jQuery.removeEvent, jQuery.removeData.

1. jQuery.removeEvent - IE fails to properly detach custom event from element,
2. jQuery.removeData - delete operator in JScript implementation do not really remove property from object, it just marks it as a deleted, so property stored in object eternally, only if it will not be overwritten or if object itself will not be deleted.
