add a main branch with a README.md when new repo is inited

[pcal43]

or maybe maintain a whole audit trail. with optional annotations from the player?

[Merith-TK]

possible implementation of this is the equivilant of

git init
<do other init tasks>
git checkout -b main
<write base readme file>
git add ./readme.md // this only adds the readme file
git commit -m "fastback main init"

since bare branches dont carry the hierarchy you could also (in a later update) generate an report file on what files had been changed (and unlikely, but if possible, how much was changed per file)
