Add multilingual support on create form

[yvangodard]

Labels of the form used to add a password does not currently support the translation (see attached for example, in french : all labels are in english). It would be interesting if this form is fully multilingual.

Good catch, looks like most of the forms do this, so lets do all the forms.

For anyone who wants to take this on as their first bug what needs to happen is that we need to add a verbose_name argument to each field with a translation string. So to do this make sure this line is in the imports section for the models.py file:

from django.utils.translation import ugettext_lazy as _

then for example to change the title field to:

title = models.CharField(verbose_name=_('Title'), max_length=64, db_index=True)

Then finally run ./manage.py makemessages to update the translations file so we can give the strings to our translators.
