v0.4 - Local media files

You can now reference local images and audio files by simply putting in a relative path (like image.png) to the .csv file. See the files in test as reference.

Version 0.3

• added support for audio files in Dialog Cards
• fixed image import in Dialog Cards

Version 0.2

• The creator now supports Dialog Cards.
• Content types are now cached locally. This means that the template files are not downloaded from the H5P Hub every time you convert a file. The repository already includes a set of H5P package templates that are known to work.
