beginning of a complete refactoring of the menues

This is an attempt to:

* get rid of the super long, complex functions in in/template.php
* make it easy for plugin authors to add their own items to any
of our menus, regardless of the used template
* continue the progress to make use of SVG in the menues

This takes a similar approach as my actionrefactor branch. Originially
I thought both refactorings could be done in one, merging the
functionality of DokuWiki actions and the menu items. However I couldn't
make it work. So instead we have two separate but similar things.
Maybe they can converge later on.

use composer based library for feed creator #1970

handle draftdeletion in draftdel action only

This was the last remaining function in inc/action.php that could be
moved to the actions.

We now have quite the elegant cascade in the action handling.

have all subscription handling in subscribe action

uses the explicit redirect abort on success

introduce a redirect action

Action can now abort to 'redirect' to explicitly trigger a redirect
back to showing the current page. Automatic triggering for post->show is
now only done when a 'show' a

always redirect to correct section

Across workflow 'show - sectionedit - save/cancel' explicitly
transmit header id to the server. So the server can always redirect to
the correct section even if headings have the same name. Fixes #1364.

allow actions to throw exception that are shown to the user

move draft saving to Preview action

This also removes duplicated code from ajax.php

drafts are for anonymous users, too. fixed Draftdel action

removed unused action methods

fixed typo in methodname

fixed paging through recent changes

Continue if there are no attributes

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

replaced some more each calls

There are still some left in the DifferenceEngine code

remove deprecated each() call

replace LESS compiler with lesserphp

This is a better maintained fork of lessphp. It seems to be fully
compatible, so this is more or less a drop in replacement.

removed deprecated blowfish class

replace some var keywords

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.

PassHash.class.php: in case of brcrypt, use the most recent variant $2y$

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

PassHash.class.php: in case of brcrypt, use the most recent variant $2y$

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.
