Log Message:
Added 'whenImported(modulename,hookFunc)' API.  This should be useful for
setting up lazily-activated initializers for third-party packages such as
Zope, Twisted, and the Python 'logging' package.  Meanwhile, it helped
clean up the kludgy "reloader" mechanism I had in there to make
'declareModule()' work.  'declareModule()' now just sets up a hook via the
'whenImported' mechanism to work its magic, instead of using a custom
reloader.  Custom reloaders for lazy modules are now in fact disallowed;
the new mechanism is more flexible and usable by multiple callers.  Errors
are also now more standardized: 'AlreadyRead' is used whenever the issue
is that something has already been read/imported.
