#310819: Do not scan for README files if "help" directory exists, even if this module has no ini file.

#307787 by KarenS: Small bug prevented modules from parenting their topics to another module properly.

German translation of full advanced help. Finally a proof of concept of fully translating the help in place exists!

* Updated German translation and file split for submodule (translation review, bugfixes and sync with core strings)

#298210 by sdboyer and me: use drupal_alter so that topics and the topic info cache can be modified by modules.
