[TYPO3-ect] Ext-JS 1.0.1

[Steffen Kamper]

Hi Joerg,

i thought about this long time. Your idea of xclassing is the only way to 
change that in core.
I was really frustrated by examine - first i got problems on every page 
where some js / ajax scripts are used, because the 
additionalHeaderData -Array isn't comfortable.
(got probs with ImageLightbox2, WEC-Map etc.)
My temporary solution is to init extjs staticly in TS to be sure that this 
libs are included before my ext-scripts are included.

Anyway i think there is a hook needed in this pagegen-script (i don't like 
the xclass very well) and the Concept of additionalHeaderData is not clear.

In TS you use a numeric array, which is good for the order manipulation, in 
php the usage  is an associative array, which can't be sort that way.
To prevent double-includes is a vision that isn't simple to realize.

May be if there is a hook, a special extension could deal that hooking that 
point and could be configurable, e.g. simple prevent imagelightbox:
plugin.tx_pageheader.headerDataFromExt {
  #no lightbox
  kj_imagelightbox2_js_prototype = 0
  kj_imagelightbox2_js_scriptaculous = 0
 ...
}

that is my vision.

vg  Steffen
