 - Created common way for themes to define extra JavaScript.  Themes can now define their
   own Messenger and/or Message objects in the `window.Messenger.themes.<theme_name>` object.
   If the theme name is provided in the options to globalMessenger as `options.theme`, the
-  defined classes will be used.  As the theme now has to be passed in as a seperate option, the
+  defined classes will be used.  As the theme now has to be passed in as a separate option, the
   `messenger-theme-x` class will now be automatically added, and does not need to be
   provided in extraClasses.
 - `MagicMessage` has been renamed `RetryingMessage`.
