Changes in progress.

I am going to make the following changes.

• to enforce the rule that at most one top-level module can globally rebind the console object, there will be a pattern like this:

var unlock = console.lock();
try {
   // application code.
} finally {
    unlock();
}

• push() and pop() wil be removed from the public API.
• the API produced by rebind() will inherit always inherit its prototype more or less directly from the global console object
• the API produced by rebind() will always inherit bindings from its parent

Completed in v0.0.8.
