Steffen has already suggested such a function. But it turned out that
there are some intricacies.

So to ensure correct load order I suggest three functions:

loadPrototype()
loadScriptaculous($module)
loadExtJS($theme='',$debug=false)

They may be called in any order repeatedly. The page rendering code will
make sure they are loaded in the correct order and extJS will be called
with the proper adapter.

If loadScriptaculous() may be called with different modules all of them
will be loaded.

extJS will always be loaded with the proper CSS. Actually I see no
reason to load it without.
