first attempt to migrate to libAV 0.10 documentation is really crappy
the cmake stuff doesn't work yet but a manual override in the config
file will get the program to build, so far the avresample() stuff hasn't
got a replacement in the new libav commenting it out (as I did) results
in a segfault
Merge branch 'refs/heads/master' into libav09fixes
fix cmake stuff (avresample is found correctly now)
resample context is initialized correctly but no sound is played.
we need avutil and avutil/opt.h to get things functional.
all function calls are converted, still no correct audio :-( help!!!
Configure reample correctly.

This means we should be able to remove the custom
pre-resample-converation, right? Still only silence :(
get libavutil math class from Cmake
Merge remote-tracking branch 'refs/remotes/origin/master' into
libav09fixes

Conflicts:
	game/ffmpeg.cc
fixed segfault when decoding audio
don't use the linesize but the number of samples
walked through the sampling code with someone from #libav channel
sampling code works correctly, issue is probably further down the path.
got some cracking noise now, at least the timestap is moving again.
this looks more neat, but still audio underruns... is the sample size
correct?
audio track can now actually be heard! but still ugly noise!
cleaned it up a little, still ugly noise
added channel multiplication for audio, slowly we're getting there
Solve a couple residual pango woes.

There were still a couple issues with the way pango handles paths to
config files when using relative references; took a while of testing
but those should be solved now.

For reference: pangorc uses CWD (as in, from wherever the launcher is
actually being run) as it’s base; not the executable path and not where
pangorc itself is either.

Additionally, deleted a superfluous copy of the app icon just sitting
there.

Solve a couple residual pango woes.
Fix osx build script to work with macports libs

Remove references to SDL2 and GLEW from cmake to let autodetection find
the libraries from macports. Remove copying SDL2 framework because
dylibbundler will handle that for us with macports lib.

Also change rm -rd to -rf, otherwise the script will fail if build dir
doesn't exist yet.
