[TYPO3-core] RFC: Refactored clickmenu to speed up the BE

[Benjamin Mack]

Commited to trunk (rev #2682).

Thanks for all your testing, both team and external. I'm glad this patch 
finally went through (I initially made it in March :)).

If something comes up during the next alphas and betas about the 
changes, just let me know.

greetings,
benni.
