Update to version 1.0.2

Changes:

- all: bug fix: Fixed compilation with the upcoming new versions
  of libebml and libmatroska.

- mkvmerge: bug fix: mkvmerge did not accept XML chapter files
  created with older mkvtoolnix versions due to deprecated chapter
  elements. Such elements are now skipped.

- mkvmerge: bug fix: Fixed negative audio displacement for a
  couple of formats.

- mmg: bug fix: Again the window handling. Hopefully this is
  better than the other attempts.

- mmg: bug fix: One was able to crash mmg by pressing 'ok' in the
  muxing dialog right after muxing finished, especially if the
  'abort' button was hit before. This mostly happened on Linux.
