There have been some z-indexes that were removed and then reintroduced
through strange merges. This is an attempt to remove all z-indexes that
are unnecessary and to clearly state the purpose of the remaining
z-indexes in a comment to each index.

In the dokuwiki standard template __background__ is the variable
defining the background-color of the content. It is one of the
guaranteed placeholder that every template must provide. Hence we should
use it with the way it is used in the default template, so other plugins
can rely on it and look consistently.
Also some other base-dokuwiki styles still use it accordingly, for
example the footnotes.

Motivation
----------
Since we do not have a dashboard it would be useful to directly see
one's task on click upon the respective icon. Also this is most likely
the dominating reason of the dashboard-usage.
Implementation Decisions
------------------------
* Use SVG: Since we move towards using SVG everywhere in DokuWiki, I
decided to use a SVG icon here as well. This makes it compatible with
other templates too, without introducing an icon-font there.
* Using a `<span>` instead of a `<strong>`: I do not see the semantic reason
behind using a `<strong>` here.
Other Changes
-------------
* The styles related to the do-plugin have been moved from
css/area_nav-usertools.less to css/plugins/do_tasks.less
This needs the respective pull request merged from the do-plugin:

The javascript of the do-plugin tries to update the container with the
plugin__do_pagetasks class. However, since our container has a different
structure than the icon produced by the do-plugin, this attempt fails
and leaves the icon in a broken state.
This commit changes the class of the container and thus ceases to be
affected by the do-plugin's javascript.
