Make the initial Mac OSX Dock the same for every user

The default user's home directory is stored at something like
'/System/Library/User Template/English.jproj'. Copy a good com.apple.dock.plist in there ('/System/Library/User
Template/English.lproj/Library/Preferences') before you create your
user accounts.
