Get EConfig and EEvent hooks working again.

There were a number of problems:

  - Walk the GType tree to find EPluginHook subclasses, instead of
    just registering the immediate children.

  - Some EConfig and EEvent subclasses were not being configured
    properly (particularly the mail and calendar subclasses).

  - Add preference window pages after the main loop starts to make
    sure all plugins and plugin hooks are installed first.
