[TYPO3-core] RFC #12089: Make messages in reports module collapsable

[Steffen Kamper]

Hi,

thx. There is a general "peekaboo" bug in IE6 which is a general problem 
of module markup i couldn't fix now but will try to fix later (has 
nothing to do with this patch)

FYI: committed to trunk, rev 6086
