Style plugin should allow refreshing of data

[damo]

Custom plugins and extensions are able to extend the list of loaded styles in the styles plugin. Unfortunately the styles plugin does not reflect dynamic changes to its list of styles and requires a reload of the whole editor to reflect the new options.

Ideally the editor should provide a way for any plugin to be reloaded without requiring the whole editor to be reloaded. Alternatively, a simpler approach to this problem would be to allow just the styles plugin to reload its data dynamically, through some additional API.

A notification could be introduced by 'CKEDITOR.addStylesSet' to trigger the reset.
