Description

For a long time "t3lib_extMgm::isLoaded()" was used to determine whether an extension is installed or not . but due to the "doNotLoadInFE" feature the result of "isLoaded" might not be enough to determine whether the extension really exists or not.

Therefore I propose to add a related "isInstalled" method.

Why is that relevant - check https://svn.typo3.org/TYPO3v4/Extensions/tt_news/trunk/pi/class.tx_ttnews.php - where "t3lib_extMgm::isLoaded('version')" is used to determine whether "versioning" is enabled or not. This worked fine for years but doesn't anymore due to the fact that "version" is not loaded in the frontend.
