Nathan Dinsmore contributed saving and loading of projects,
ypr-Snap! project conversion and countless bugfixes
Ian Reynolds contributed handling and visualization of sounds
Michael Ball contributed the LibraryImportDialogMorph and countless
utilities to load libraries from relative urls
Bernat Romagosa contributed more things than I can mention,
including interfacing to the camera and microphone
