TYPO3 Core

extList was kept next to the new extListArray in LocalConfiguration.
Both hold the current list of loaded extensions. This leads to
confusion which variable is the one that takes precedence.
The patch removes extList from the upgrade wizard in the install tool
and only writes extListArray. This way, only one key is kept in
LocalConfiguration.php. For compatibility reasons, they array entry
'extList' is added to $GLOBALS['TYPO3_CONF_VARS'] at runtime during
bootstrap.

Patch set 2 for branch master has been pushed to the review server.
It is available at http://review.typo3.org/16566

hint: gov, intro and dummy packages need to be checked if they ship extList, too.
