Some improvements

* Added contributors list to `composer.json` (linked to github contributors graph)
* Improved Behat context
* Fixed/Cleaned/Tested configure options handling
* add `--default` option to `install` command
well, for the configure options, it may be possible to pass an option file (better than creating a weird syntax to pass the values in a CLI option): ``pickle install --build-config config.json`` (or whatever format we decide to use for the config file)

For the logs, are you talking about the build logs only, or could it be the full output ? In the second case, the shell does it for us (assuming we display the build logs in verbose mode rather than based on an interaction): ``pickle install -v -n > pickle.log``

``--no-interaction`` (with its ``-n`` shortcut) is already the way to disable all interactions
