[Twisted-Python] Jelly and Components

[Andrew Bennetts]

Instead of 
    class Foo(jelly.Jellyable):
        # etc

Shouldn't we be doing:
    class Foo:
        __implements__ = jelly.IJellyable
        # etc

or:
    class Foo:
        # etc
    
    components.registerAdapter(..., Foo, jelly.IJellyable)

?

This strikes me as being like copy_reg, but better :)
