  de/de-informal: localization updates (delete user function)
  unit tests for self deleting of user accounts
  FS#2751 - self deletion of user account

When the DokuWiki install was in a deep namespace, the used path name
could land in the >100 char limit and trigger ustar format where the
filename and directory name are split. This would fail the test.

This reverts commit d6d85509.

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

Translation update (zh-tw)

Tars strip the leading slash so the tests where wrong. Not sure why they
stilldid work sometimes

Improve nofollow behaviour for ?do=index

and no automatic sitemap.xml is being generated.

de/de-informal: localization updates (delete user function)

this ensures nested POST data is correctly encoded

In debug mode: catch and log JS errors with file information

The check if the plugin is enabled is done later in the plugin
controller anyway.

added loggedIn class to main tpl container

Fixes validation problems with base64 encoded images in CSS.

Fixes validation problems with base64 encoded images in CSS.

add TEMPLATE_DOKUWIKI_PAGETOOLFLOAT_DISPLAY event to template

also made it more secure against copy'n'paste

Implemented some ARIA attributes

In response to FS#2766
- make namespace links in the browser sitemap nofollow
- remove nofollow from browser sitemap link on the wiki start page
  when sitemap.xml generation is disabled

FS#2770 - prevent <file> and <code> syntax regex matching too much

code - test correct recognition of downloadable filename token
file - test correct recognition of syntax name & downloadable filename tokens

The current message confusingly mentions bad 'username' when username is not involved.  The
new message is the same as that introduced for an incorrect current password on the self
delete profile form (FS#2751)
