[TYPO3-core] RFC: Bug #7669: Change elderly while(list()=each()) to foreach calls in t3lib_tstemplate

[Oliver Hader]

This is a SVN patch request.

Problem:
There are many old while(list()=each()) calls in t3lib_tstemplate. Some 
of them are buggy becaus the internal array pointer has to be resetted 
then walking through an array by each().
One current side-problem is that in some PHP5 versions TypoScript 
constants are not substituted correctly - due to a missing reset($array).

Solution:
Change these iterations to use foreach() and clean up the whole class a bit.
