[Dev] New parcel loader coming

[Morgen Sagen]

Ok, I just modified most of the files in the tree, but I've  
triple-checked that everything still works on all three platforms.  The  
biggest change you'll notice in parcel.xml is that all the repository  
paths we were using as namespaces have been turned into real URIs.   
Each parcel now has a URI which conveniently defaults to  
http://osafoundation.org/parcels/<relative path to your parcel.xml>,  
but you can override that (third-parties will need this feature, for  
example).  Error reporting during parcel loading should also be a bit  
better, and will keep improving as I come across more conditions to  
handle.  For example, if the loader encounters an XML-parsing or  
class-importing error, it will print the xml file and line it was on,  
the exception that occurred, and an exception with the original  
traceback (not the traceback of the handler that caught the exception)  
will percolate up to the top and get printed to the console (you won't  
have to see the log file for the stack trace).  Hopefully this change  
will also help within Wing.
