Adding "Simple Plugins" seems unused

[arielpollack]

Hey, not sure if I missed something, but it seems that all the of the "Simple Plugins" related code doesn't actually do anything.

You can add and remove plugins, but nothing in the text view's code is updating it. There's actually no method in HKWSimplePluginProtocol that informs the plugin about changes in the text.

Did I miss something or it just an abandoned feature?

I actually want to implement another plugin that handles inserting bullets/checklists to the text view and the simple plugins mechanism seems to be the way to go here, but digging into its code I can't really use it for my purpose.

Thanks!
