[wp-hackers] Adding JS to a Page based upon the used shortcodes

[Alexander Beutl]

Thanks Casey and Otto,
that seems to do the trick at least for "standard templates" with only a
single loop.

the only remaining thing is:
I will also need to know which methods are used inside the template - but
there I may aks the user to specify which scripts should be enqueued on each
page load because they are used in template... (I think this is still better
then scanning all template files which would be an enormous performance
waste).

Maybe I will add a fallback to add the script in body when it wasn't added
to head allready since this is still better than if it's missing.
