Fix jQuery #13251: use slice instead of substr
Make the native check support Rhino. Close gh-185.

In Rhino, native functions do not display as just [native code],
but often with extra information, for example:

   js> Array.prototype.slice
   function slice() { [native code for Array.slice, arity=2] }
Fix the slice check. Close gh-184.

As of 9751a47ded9693140af2aa635f7a9d928ac30a0b, docElem is not defined
at the point of its use in the slice check, so it always fails, and the
native slice never gets used.

Avoid use of dynamic attributes with innerHTML. Close gh-190.

Some environments (Windows 8 Store App) will not permit the use of
innerHTML along with dynamic attributes like 'name'. You can, however,
set them via the setAttribute method. This should help those migrating
their code from the browser to a native application.
