This undoes the change in alignments. Those are useful when displaying
text only emails in a monospace font.

As discussed in https://github.com/splitbrain/dokuwiki/pull/2462#issuecomment-413786942

The newlines serve the goal of keeping textlengths reasonably short in
text only mails.

This change was done by reverting the files back to the current master.

As discussed in https://github.com/splitbrain/dokuwiki/pull/2462#issuecomment-413786942

This applies a lot of formatting fixes on the language files:

1. In EOF - trimmed all empty lines except one
2. After the title - one empty line strictly
3. Corrected links to national versions of documents in dokuwiki.org if
   they exits - 4example [[doku>namespaces]] to [[doku>ar:namespaces]]
4. Corrected some over-auto-translated links to "playground:playground"
   and "wiki:syntax"
5. Torn lines are collected in one in a large number of places (except
   for RTL languages)
6. Removed e-mail signatures that now is missing in the English set of
   files

- jQuery to 3.1.1
- jQuery UI to 1.12.1
- jQuery Migrate to 3.0.0

There are a few warnigs from migrate that have to be fixed. The toggles
in the Media Manager are also missing their proper icons.

Default only text string exists, via localized translation a wiki admin
can add his/her own (html) version.

mailwrap.html is back

@EMAILSIGNATURE@ added

Additional bug fix

Done:
Cleanup of the mail text signature.
The signature is deleted from the txt files and moved in to lang.php
Mailer.class.php updated to insert the signature

Fix:
- Cleaner text
- no more "-- "  "--" "---" "----" problems.
- mailwrap.html is not needed anymore an can be deleted (?)

Changed files in all languages:
lang.php
mailtext.txt
password.txt
registermail.txt
subscr_digest.txt
subscr_list.txt
subscr_single.txt
uploadmail.txt
pwconfirm.txt
showrev.txt

delete?:
mailwrap.html

Added german translation for file-in-use reference

This now pulls all data from official jQuery sources. Either their CDN
or their github account. Google tends to serve outdated or even broken
files :-(

Unfortunately there's no simple way to get the latest stable jQuery-UI
so for now the version has to be adjusted manually in the script.

This reverts commit 524df576.

Conflicts:
	inc/lang/bn/lang.php
	inc/lang/fr/lang.php

this has been done by a script and might not be 100% accurate

Remove whitespace from end of lines to reduce the number of CodeSniffer
violations.

/ fix several typos / Fixes FS#2821

This was updated in the english translation a while ago, but was still
missing in some translations
