[support] Javascript and CCK fields

[Carl Wiedemann]

If you don't care that the JS is added on every page, you might as well put
it in hook_init. Otherwise if you want to use the same JS on multiple forms
you would need multiple #after_build or #theme callbacks, which is
repetitive and a little messy. Write your JS so that if indicative elements
aren't present in the DOM it returns early.
