[TYPO3-english] deleting very old extensions

["Christian Müller (Kitsunet)"]

Hi Katja,

if the extension is not active it should be fairly safe to just delete 
them from typo3conf/ext. Only Exception might be if someone included PHP 
/ JS / CSS from those folders directly through Typoscript, which is 
possible even if the extension is not active. Safe way is to first 
rename or move the folder, if (after clearing the cache) everything 
still works fine delete it.
