Most common use case for TCA type "group" fields is
the usage of "internal_type=db". Therefore, this
option is now the default value. This allows to
simplify corresponding parts in FormEngine,
Datahandler, etc. Furthermore are all Core TCA
files adjusted and do no longer define this
option for type "group".
