set paths in help tree file of MediaWiki extension help

we set the paths here to their runtime values, because in new
build "paradigm" English tree is not updated, just copied. No
problem with that, we'll fix regressions later. Now it works
even in en-US build, but nodes are not localized, because
update_tree.pl does not find localizations due to the changed
paths. update_tree.pl is a hack and must die. It will be killed
in feature/killsdf branch.
