[TYPO3-core] RFC: custom toolbar icons in the Page module

[Franz Holzinger]

Hello Dmitry,

> 		'icon' => array(

> 			'attrs' => 'hspace="2"',

> 		'link' => array(
> 			'url' => 'edit.php',
> 			'onclick' => 'alert("Bum!")',
> 			'title' => 'Click to BUM!',
> 		),
> 	);

> More complex but more usable. What do you think?

I have written a new patch which gives you more enhanced flexibility for the 
future. Maybe parts of this code could be used also with arrays coming from 
TypoScript or anything similar, so I have use the $tmp['a.'] array notation. 

I will rewrite the API documentation on the wiki when the code has been 
approved.
