Translation update (ko)
Fix for update messages never completely going away

The existing logic for messages.txt requires some valid update
response (ending in %) to the messages update check before it clears
the current messages.

However update.dokuwiki.org appears to return an empty string response
if everything is up to date. (ie http://update.dokuwiki.org/check/46.1 )

As a result if there are update messages in messages.txt they don't
automatically go away after updating to the current version. The only
time they change is when a newer release comes out. The upgrade plugin
has logic in it to force a re-download of messages.txt, but currently
this just re-downloads the old update messages.

This change explicitly allows for "" as a valid "no messages"
indicator (distinct from false, which is the HTTP error indicator.)

AUTH_USER_CHANGE handler can modify passed data

Originally AUTH_USER_CHANGE handler could modify the user data, however,
auth plugin consequently worked with different copy of the array thus
effectively preventing any changes by the AUTH_USER_CHANGE implementer.
