duplicate message handling improvements

- lrelease will not abort on duplicates any more
- lconvert now gets noisy, but only if messages within one file are
  duplicated (combining files with identical messages is ok)
- lupdate stays silent, but will eliminate duplicates again

- consolidate handling of dual-encoded and duplicate messages - for
  performance
- instead of the format loader, now the app is responsible for calling
  the duplicate handler. this allows for the fine-grained control
  necessary for optimal performance.
