Merge branch 'open-files' of git://github.com/nathansamson/diveclog

* 'open-files' of git://github.com/nathansamson/diveclog:
  Report errors when opening files
  Make it possible to load multiple files at once.
  Open File works. I refactored the code and introduced a new type. I never used it as a pointer (their was no real reason), but I'm not really satisfied.
