/**
* Inserts the common ajax javascript files in page header.
*
* Insert the common ajax javascript files (prototype, scriptaculous) in the
* page header using page vars. <i>All other javascript files have to be added
* manually on-demand using the {@link smarty_function_pageaddvar() pageaddvar} plugin.</i>
*
* Available attributes:
* - modname (string) the module name in which to look for the base javascript file for the module; defaults to top level module when used in a block template.
* - filename (string) (optional) filename to load (default ajax.js)
* - noscriptaculous (mixed) (optional) does not include scriptaculous.js if set
* - validation (mixed) (optional) includes validation.js if set
* - lightbox (mixed) (optional) includes lightbox.js if set (loads scriptaculous effects if noscriptaculous is set)
* - imageviewer (mixed) (optional) includes Zikula.ImageViewer.js if set (loads scriptaculous effects and dragdrop if noscriptaculous is set)
* - assign (string) (optional) the name of the template variable to which the script tag string is assigned, <i>instead of</i>
* adding them to the page variables through PageUtil::addVar
*
*
* Examples:
*
* <samp>{ajaxheader modname='Example' filename='example.js'}</samp>
*
* <samp>{ajaxheader modname='Example' noscriptaculous=1}</samp>
*
* @param array $params All attributes passed to this function from the template.
* @param Zikula_View $view Reference to the {@link Zikula_View} object.
