Hi,

Would you be interested in a pull request to make the ChangelogTypes configurable?

This is to support anyone who uses a different set of tags in their changelog. It's already possible to configure the tags for minor/patch version bump; this would extend the configurability to the changelog generator.

My idea was to pass an additional config option pointing to a JSON configuration file containing ChangelogTypes. If not specified it would use the existing hard-coded types.
