Update Typo3.gitignore for CMS v6.2

Typo3 now has an official way of overriding Configuration (AdditionalConfiguration.php).
/t3lib has moved into the /typo3 Directory.
Removed v4 specific ignores because it is deprecated and should no longer be used.
There were ignores missing for the symlinked setup.
