[FreeNX-kNX] Solved "evdev" keyboard mapping issues.

[Jeremy Wilkins]

Thank you for your post Troban.  We will test your patch to see if it needs
revision and submit it to the freenx-team ppa for inclusion testing for an
upcoming bug fix release.  I don't think there is a problem with your patch. 
I just need to make sure we haven't left out another area in nxnode that
could use this change as well.
