Dutch translation improvement

[GordonFFS]

I tried to send a complete dutch.lng to admin Zenju, but I can't find the mail-or-personal-message option...

So here it is. These are 2 existing lines:
<source>Updating file %x</source>
<target>File %x bijwerken</target>
Because everywhere in this lng file, the sourceword "File" is replaced with targetword "Bestand", I would suggest to change the targetline to:
<target>Bestand %x bijwerken</target>

That's it.
Kind regards.

Done, thanks!
