Add the possibility to create add-ons / modules

It would be great if we could abstract the js autocomplete portion of the plugin so people could easily extends with their own behaviour and trigger key. For instance, having a an add-on to be able to autocomplete shortcode name.

Add to this the ability to insert attachments/media, probably using a different trigger character. Would be extra useful for big publishers/bloggers who use same media multiple times. It'll also need to override the default autocomplete list style to allow an image in there.

A far-aimed module would search the web for something, or match twitter names.. lots of possibilities here.
