 - Change hostname.c to make translation easier.
 - Update pt_BR translation.
 - Rebuild net-tools.pot and merge the other .po files (me).

Patch from Thorsten Kukuk

Fixed man pages (only German and English one).

Add blurb about automagic subnet arp.

For the de and en Versions I also added a short note on how it is useful

the offending sentence.
