[TYPO3-formidable] Install tool broken in TYPO3 4.4.1/4.3.4 if ameos_formidable is installed

[Oliver Klee]

Hi all,

it looks like the install tool login is broken in TYPO3 4.4.1/4.3.4 if
ameos_formidable is installed. Particularly, the session fixation fix in
the install tool gets broken by this line in FORMidable's ext_localconf.php:

if(!isset($GLOBALS["_SESSION"])) {
    session_start();
}
