Translation update (eu)

the new version of the validator is static. But it makes sense to use a
single point of entry anyway, so instead of adjusting the use of the new
class, prefer the function.

Various plugins access the form members directly currently.

Adjusted pattern for matching media links to properly handle a single '}' in the link text. Fixes #1587.

Added green and red text color styles for geshi. Improves look of highlighted code for language diff. Fixes #900.

The internal lang and localized variables of a plugin are no longer
accessible from the outside. This adds a proper setter and also fixes
the type hinting in the config plugin.

If an entry in the loop at `_tpl_metaheaders_action` has no content, skip this entry.

There are still some left in the DifferenceEngine code

this fixes another problem with our tests and phpunit 6.1

This fixes a problem with those tests in the most recent version of
phpunit. I thought it was caused by the use of the deprecated var
keyword, but some other weirdness was going on. This way it's more
proper anyway.

This should fix some tests on PHP 7.1. The work is far from done, we
still have a lot of variables without proper accessibility defined.

This change breaks compatibility with php 5.3.7, but a standing
requirement for at least php 5.6 is declared in composer.json.

If the php documentation is to be believed, this change increases
security against pass-the-hash type attacks. (I do not have the knowledge
to assess the security differences between $2a$ and $2y$).

As a Sidenote: htpasswd shipped with apache2 2.4.10 (and probably,
other versions), when used with the -B (=bcrypt) option, produces hashes
marked with $2y$.

Nonewithstanding the actual support or non-support of $2a$ by the
apache2 'AuthUserFile' directive, the apache 2.4 documentation only
asserts support for the $2y$ bcrypt variant.
Therefore, this commit would make it possible for dokuwiki and apache2
basic authentication to share the same password file, in the case when
bcrypt is used.

* Updated remote.php

Updated remote.php for retrieving all the acl details.

* Updated remote.php

By mistake changed in addAcl instead of listAcls.

Those tests either just check that an exception is NOT thrown or are
there to check dependencies for other tests. Newer phpunits mark all
tests as risky that have no assertion.
