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

[Bastian Waidelich]

Hi Steffen,

I remember talking about this.  Great, that you actually implemented it!

However I have a concern (sorry): If collapsed, important warnings could 
be easily overlooked.. So I'd suggest to collapse all categories by 
default _unless_ they contain warnings or errors - instead of storing 
the states in the BE user settings..

What do you think?

keep up,
Bastian
