Remove 2 unused number tags in Construction Mode GUI These numbers are shown aside the power tag, but the numbers never change. They don't serve any purpose and are just visual clutter and annoying, since they partially overlap. They are probably a leftover from copying code over from other scripts. With this changeset, only the power and turn time are left visible, as it is supposed to.

# - Try to find the OggVorbis libraries
# Once done this will define
#
#  OGGVORBIS_FOUND       - system has both Ogg and Vorbis
#  OGGVORBIS_VERSION     - set either to 1 or 2
#  OGGVORBIS_INCLUDE_DIR - the OggVorbis include directory
#  OGGVORBIS_LIBRARIES   - the libraries needed to use OggVorbis
#
#  OGG_LIBRARY           - the Ogg library
#  OGG_INCLUDE_DIR       - the Ogg include directory
#  VORBIS_LIBRARY        - the Vorbis library
#  VORBIS_INCLUDE_DIR    - the Vorbis include directory
#  VORBISFILE_LIBRARY    - the VorbisFile library

### sommer [SuperTux]
##  - Removed unused vorbisenc library
##  - reversed order of libraries, so that cmake 2.4.5 for Windows generates an MSYS Makefile that will link correctly

### koda [Hedgewars]
##  - split ogg and vorbis lookup
##  - special case for framework handling
##  - standard variables handling
