* Many changes to the way settings are handled, including allowing them
  to be dynamically reloaded at run time.
* Nascent support for configuration GUI (still needs work).
* First pass at key and word echo (still needs work).
* Added support for ~/.orca/orca-customizations.py, a file that will
  not be overwritten, but will also be loaded if it exists.

  which key(s) are to be used as the Orca modifier key.
* Refactor of script.py to include methods for getKeyBindings,
  getBrailleBindings, getInputEventHandlers, and getListeners to make it
  easier for subclasses to override these things.

  a per app basis.
* Fixed the way localized files were being found and used.
* Reduced repetitive verbosity.
* Reincorporated nascent support for magnification (still needs work).
