Tor Lillqvist 95de5a74cc Rename our Objective-C Document class to CODocument 
There are already several classes called Document on the C++ side.
Let's reduce confusion a bit. (Also, we might need to use the
Objective-C Document class from some of the Online C++ code (which is
actually compiled as Objective-C++).)
