[TYPO3-project-formidable] Patch: use the form ID when adding header data

[Oliver Klee]

Hi,

this is a change request.

In the seminars extension, we render a form twice: one time for checking
whether the second page of the multi-page form is reached, and then the
second page.

This leads to the JavaScript getting added to the HTML HEAD twice,
resulting in multiple event handlers attached and in multiple form
submissions in IE.

To fix this, the header data should use the form ID (plus a prefix to
avoid name collisions) as array keys.

I've attached patches for the 1.1 branch and the trunk.

Thanks,


Oliver
