[CM] iconography

[Heinrich Taube]

Grace an GraceCL now have tobias kunze's pretty application icon  
(lambda on music staff) on MacOS and WIndows. Thanks to Andrew  
Burnsons for showing me how to do this!
I can probably get an icon associated on linux too if someone can tell  
me the schell commands that would associate an icon with an executable.

to get the icons you need to reissue premake and rebuild the app

cd cm
svn update
premake --clean
rm -r bin obj
premake --verbose --target gnu --sndlib ../sndlib
make
(WIN:  premake --target vs2008 --sndlib ../sndlib )
