This does not fix FS#2677, it only adds support for fixing it later.

This time the test case was correct and actually showed a bug in the tar
library. The error occured only on the first build (directory build/0/)
where the zero was stripped from the path name.

I added unit tests to the cleanPath function and discovered another bug
with handling relative directories. I rewrote the cleanPath() function
and now it should finally work.

Unit tests FTW!

also allow the order to be specified in more places.

Currently the search box is below the media file list, where it is
effectively inaccessible in a namespace with lots of files.  This
change moves the search box above the media file list and below the
upload form.

This is another go at what pull request #227 tried to do. This removes
support for a style.local.ini in the template file in preference of a
style.ini in the conf folder

- %GROUP% & %USER% can now both be used in the same rule, e.g.

%GROUP%:%USER%    2

- rules with tokens will be skipped when the user is not logged in
  previously %USER% was attempted

/ fix several typos / Fixes FS#2821

Fixed some issues which occur whenever RTL and LTR languages could
potentially be mixed, using the HTML5 `<bdi>` element.
This element is currently only supported by Chrome and Firefox.

The old and only partially working fix for tpl_breadcrumbs() was removed in
favour of this solution.

This reverts commit d6d85509.

I guess it was a bit too early to think straight :-/

and no automatic sitemap.xml is being generated.
