create default 'community health files' for Bonsamurais org & repos

[tmillross]

See: https://help.github.com/en/articles/creating-a-default-community-health-file-for-your-organization
Following this standard practise allows new repositories to include default readme, code of conduct, contributing guidelines and support files.

• create .github repo
• create default CODE_OF_CONDUCT by copying text from the hackathon one
• delete hackathon COC
• replace any links to the hackathon COC with new one (if necessary)
• create default SUPPORT file (draft in-place - what else should it say?)
• create default CONTRIBUTING file (what should it say?)
  • holding off on creating this until input received from software recommendations team
