updates for the updater and the diff engine.
- this update also includes an important change for including the diff engine, since we may need to include an updated engine before updating. This basically means that for a future update (B4 to another version) requires copying the new diff files first... the new include method should prevent this needed handwork for later versions then. git-svn-id: file:///svn/phpbb/trunk@6695 89ea8834-ac86-4346-8a33-228a782c2dd0
