[TYPO3-mvc] FYI: committed some small cleanups

[Franz Koch]

Hey there,

I just committed some cosmetics and cleanups:

- fixed doc comment (we no longer have a 
Tx_Extbase_Persistence_RowInterface)
- use foreach instead of a while/list construct in 
Tx_Extbase_Utility_Arrays (is supposed to be faster)
- in Tx_Extbase_Utility_ClassLoader require files only once (just in 
case, had a issues with this once)
- Tx_Extbase_Persistence_Backend: use a existing object method to check 
for lazyLoaded properties instead of repeating the code in a if-condition


I'm not familiar with the FLOW3 trunk - maybe the change in the 
persistence backend can also be applied there?


Happy extbase 1.2.0 then :)
