check for new $branch_name and $repository in .env

This means that the .git/config does not have to be changed manually every time, but the script now checks whether changes have been made and adjusts them automatically. Branches are now added automatically if they do not yet exist.

Also beautify the code a bit:
- add some comments
- removed tput as this is not used i.e. in the mainsail ui and leads to confusing/unnecessary output
