BundleClassLoader in osgi-ified prototype.

[Rick McGuire]

David,
I was digging through your sandbox code and found the BundleClassLoader 
implementation.  In order for this to be generally useful, it's going to 
need to handle resources as well as classes.  Is there some reason why 
this is not implemented here?  If it's just something that's on your 
todo list, I wouldn't mind adding that piece.  I'm going to need a class 
loader like this for doing an RFC 66 implementation, so it's either fix 
this one to be complete or write another version.
