This commit looks a bit crazy at first glance. It (re-)introduces lots
of whitespaces and bad formatting.

Explanation: Backporting upstream changes lead to commits being
applied out of order. This meant a lot of manual intervention which in
turn lead to slight differences between upstream and NX.

With this commit these slight differences are minimized which will be
of great help when adding further upstream patches.

  - Update XErrorDB to latest X.org version.
  - Install XErrorDB, XKeysymDB and Xcms.txt to /usr/{local/}share/nx/.
  - Assure that libNX_X11 finds those files at the
    named location.
  - Update debian/ packaging files.
  - Update nx-libs.spec packaging file.

Fixes ArcticaProject/nx-libs#153
