A better new_project.sh (#5191)

* A better new_project.sh

* Fix docstrings

* Use single quotes for anything not shown to user

* Missed this docstring

* Simplify get_git_username()

Thanks @vomindoraan

* chmod +x

* Add docstring for print_error()

* Break up git username call into multiple lines

* Use with statement here

* Conform to PEP 8 even more

* Turn it back into a shell script

* chmod +x again

* Update docs to reflect new keyboard generator usage

* Tweak wording slightly

* Trim trailing whitespace

* Don't actually need to escape the newlines here

* As I suspected, you can pass shift a number

* Prepend ./ to match the other code block

* Minor syntax tweaks

* The username token has changed

* Replace name in the readme too

* Make some reasonable assumptions about the presence of Git
