Official docker image

[rudolph9]

Is there interest in supporting an official ditaa docker image? I did a little work updating this old one to support the latest version of ditaa chai2010/ditaa-docker#1
and also added good unicode support chai2010/ditaa-docker#2

I think it would be a big! boost to the project if we could iterate on the above a little and document some example and make the usage flow really convenient for newcomers to the tool to make use of ditaa via the docker image and officially link it the doc.

Thank you @rudolph9, this is appreciated by me.

I've just discovered ditaa, and the docker container got me up and running immediately.
