[factorio_development.sh] Fixed switching back to development version in info file:

- The sed expression was a bit too trigger-happy in replacing version
strings used in dependencies.
- Bump the year in copyright notice.

[factorio_development.sh] Expand deployed files for new mods:

- Include stock text for a couple of sections in the README file.
- Mark build script as explicitly being released under a GPLv3
license.
- Include Emacs editor configuration file for setting the fill column
to a biter saner (larger) value.
- Include an empty control.lua file with helpful header stating
copyright and license (for easier copy/pasting from it).

[factorio_development.sh] Fix short usage instructions for release command:

- First argument is mandatory and has to be release version.

[factorio_development.sh] Make mod directory path optional for init command:

- Default to using the working directory as root.
- Bump the version, initial feature-complete release.

[factorio_development.sh] Include development script in mod directory during initialisation:

- Makes it simpler for people to use the scription without having to
fetch it from external location.

[factorio_development.sh] Use long options for git commands where available:

- Improves readability of code.

[factorio_development.sh] Added (personal) workaround for tag signing:

- Older versions of git (<2.23) do not have the tag.gpgSign
option. Try to emulate it by appending the --sign option if it is
set in git configuration.

[factorio_development.sh] Fix changelog updates and drop release archive when aborting the release:

- It is not possible to read from and update the changelog file at the
same time.
