RC - Release candidate 1.4.0rc1

- moved to semantic versioning, e.g. `major`.`minor`.`patch`;
- added `rc1` suffix for release candidate;
- added `extras_require` entry to `setup.py`; and
- deleted redundant `sonar-project.properties`.

The `extras_require` entry allows `testing` and `setup` packges to be
installed, for example `pip install -e .[testing]` will install fido with
its `tests_require` packages also. `pip install -e .[setup]` installs the
`setup_requires` packages. `pip install -e .[testing,setup]` works as you'd
hope :).
