Forgot to prefix an Exception with the root namespace.
Add a getPreviousSection method on the changelog parser.

This is useful for getting the previous version, regardless of how many point releases the version may have jumped.
ie: 1.0.1, 1.0.2, 1.1.0.
Switched the private method getEntriesSorted to public.
Add automatic population of the changelog directly from GIT commit logs!

This allows you as a developer to stop copying changelogs into commit messages, but use GIT as it was meant to.... finally.
