migrate into dokuwiki organisation

[Klap-in]

Some suggestions for repositories to be moved in the dokuwiki organisation:

• https://github.com/splitbrain/dokuwiki-plugin-xref
• https://github.com/splitbrain/dokuwiki-extensionmirror
• https://github.com/splitbrain/dokuwiki-plugin-pluginrepo
• https://github.com/splitbrain/dokuwiki-plugin-dokuteaser
• https://github.com/splitbrain/dokuwiki-plugin-dwquick
• https://github.com/dokufreaks/dokuwiki-translation
• https://github.com/splitbrain/dokuwiki-stickbuilder

Probably there is more handy stuff related to dokuwiki.org? The dokuwiki organisation has not its own issue tracker for stuff like this?
