This adds $INPUT in all places where it was still missing and available.
$INPUT is now also used in places where using $_REQUEST/... was okay in

This makes it possible to find words that include soft-hyphens. However,

This reverts commit 58a22bd0.

It was accidentally pushed to the repo.

$NS is only used in lib/exe/{ajax,mediamanager}.php when no $ID context
is present. The two functions which use $NS in inc/template.php are only
called through those both endpoints, not through doku.php. In doku.php,
$ID is the only correct value, $NS is not kept synchronous with $ID.

Use getNS($ID) in functions which are called through doku.php.
