Use a env var provided by Fabri instead of interactive_mode

Cause we can not override its value as it's defined in a file

See merge request !7

active_mode, cause we can not override its value as it's defined in a file

Provide languages in a variable in conf file

Plutot que ne proposer que le français comme langue en plus de l'anglais, on ouvre les possibilités en gérant les langues additionnelles via un paramètre : env.site_languages. Tout ça pour builder des plateformes prêtes à accueillir des langues supplémentaires.

Voir l'option **--translations** de la commande make pour les valeurs possibles : https://drushcommands.com/drush-7x/make/make/

Feature/git dirty repos

Add a git "module" that checks if workspace repositories are clean or not.

If not, asks if user wishes to continue with consequence of potentially loosing local files/commits/modifications.

See merge request !5

to detect local branches ahead of remote branches

Add a <tags> argument to the <test> command

We can now filter which scenarios are run by behat.

+ propose to push local branches

It was confusing to test on a string but passing a boolean as the default
value.

The drush.make command is the one dangerous method. The test should be
done there and not on all methods calling it.

Refactored git related methods from __init__.py to it's own git.py module.

The repository is not always "represented" by a .git directory. It can
be represented by a .git file in the case of a git submodule.

Better to fetch local branches information once instead of twice.

We play with "in memory raw data" and extract needed information as
needed.

We wouldn't want to loose unpushed code!

Extracted a couple of functions and it made it "clear" how to avoid
storing two lists of branches in memory.

We can now filter which scenarios are run by behat.

Bug/site name

We need quotation marks so that the site name will be whole and not multiple arguments to drush.
