Mojos marked as thread-safe

- I followed the Maven documentation about thread-safety and it seems that
  even the inplace goal is thread-safe in this meaning. Obviously it is not
  recommended to process the same file several times, especially with multiple
  threads, but that scenario is not what Maven means by the thread-safety.
