(commit fb46ebd8)

This commit adds new strings to the de/de-informals files which
have been introduced through the new Media-Manager.

All lang.php-files in inside en/de/de-informal have been
reordered and reformatted.

This adds support for the config_cascade when enabling/disabling plugins,
making farming easier.
The changes have been implemented by Piyush Mishra and are a part of the
new extension manager which will follow later. It's the result of a
Google Summer of Code project, the official project page can be found at

Thanks to Piyush for the work and Google for sponsoring it!

This introduces a new media manager and media revisions to DokuWiki. The
changes have been implemented by Kate Arzamastseva and are the
result of a Google Summer of Code project, the official project page can
