Make all hogs say Yessir taunt on their turn start (replaces revenge taunts) Rationale: The taunts Illgetyou, JustYouWait were fairly odd and almost always inapproriate to the situation as most voicepacks clearly assume these to be used for revenge only (e.g. “You'll gonna pay for that.” was played at turn start because of this.).

# - 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
