auth.ftp, fix user-facing enlish, add german translation

Minor spelling issues found in english part while adding
the german translation.

Bumps the copyright year as well.
auth.ftp: Authentification -> authentication

Fixes english translation, yet impacts others.
auth.ftp: Search/replace occurences of connexion
auth.ftp: Repository -> Workspace

Reflect the (english) naming that Charles mentioned
should become used in Pydio instead of repository.
auth.ftp: Try to improve meaning

Actually the french translation looks much closer to the actual use of
of the auth.ftp module. It only verifies credentials against an FTP server
but doesn't actually open workspaces/repositories.
(well, actually only for testing the connection)

The Portueguese translation looks as if it was translated from the
english one. I can't fix it without being familiar with Portuguese.
auth.ftp: Reword description for the workspace ID
auth.ftp: Reword the FTP login screen (yes/no) description

It is now closer to the french translation which - when comparing
against interface and documentation looks more like it says what
it eventually does.
auth.ftp: Allign english with french translation

Looking at the french translation and the user interface reveals
that this doesn't eventually have anything to do with testing the
connection but actually being the workspace used to validate credentials.

Since the translation in english was misleading I tried an automatic
translation of the Portoguese string as well, but is is far from
optimal.
auth.ftp: Fix self-inflicted translation after peer-review
auth.ftp: Add german translation for configuration parts

The configuration part is now added after shuffling things
around in the french and english translation.
access.ajxp_user: Translate some german strings

Where I'm quite certain they're correct.
access.ajxp_home: Getting started translated to german

This was forward-ported from a patch we had against 5.3.1 and
mostly completed the "getting started" section translation.
