[TYPO3-core] RFC #0011317: Backport treelist caching from TYPO3 4.3 to TYPO3 4.2.6

[Benjamin Mack]

Hi Rupi,

looks good. But as this is non-critical for the 4.2 branch, I ask you to 
check with Ingo if he wants this in there.

btw: I'd be interested in the speed improvements between 4.2.6 and 4.2.7 
- with the typolink improvement I can imagine that tt_news and 
especially stuff like tx_cal should be flying now. Thanks A LOT!

All the best,
Benni.
