So. First pass. Add secondary explosions to RateExplosion and RateShotgun. Not yet added to shoves. This is of limited utility at present since the dX has to be small since we can't bother tracing all hog motion. But, should be more useful once shove is added, and tracking of explosives and mines.
# - 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
