Currently the translation:
"Notify me by email when someone comments on my proposals or debates"
It only refers to proposals and debates, but actually it also refers to budget
investments, topics and polls.
We add new method set_user_locale to render the page
with the user's preferred locale.
Note that we add a condition 'if params[:locale].blank?'
to recover the user's preferred locale. This is necessary
because it may be the case that the user does not have an
associated locale, and when execute '@user.locale' when
this value is 'nil', by default returns the default locale.
As we do not want this to happen and we want the locale we
receive as parameter to prevail in this case.
You can update the same "notifications" section that we allow you to
update in "my account".
This "subscriptions" section differs from the "my account" section
because we do not need to be logged in to update the status of the
notifications.
