Redo orgchart to require generation as source
Changes:
1. Remove the text diagram from project/orgchart.adoc and put it
in project/orgchart.ditaa
2. save a generated png in project/images
To generate a new diagram on Fedora
dnf install -y ditaa
ditaa project/orgchart.ditaa project/images/orgchart.png
---Justification---
Having ditaa as a build requirement is rather heavy and currently
a non-starter in the CI system ...
In the interim, and possibly forever, I'd like to see us make this
a source requirement.
