Fix the input in the demo.

We had some over zealous can-focus's set to 0 which was the main issue. The
other stuff was just stuff to clean up I found along the way.

Testing Done:
Ran the demo verified I can input text. Sending is still broken but that's another matter entirely...

Talkatu is a collection of Gtk+ widgets that are useful for chat applications.
It was started as a rewrite of the GtkIMHTML widget found in Pidgin, but
quickly expanded to include most things related to conversation windows.
This is highly experimental right now and might eat babies, we're not sure
yet. So proceed with caution :-D

to also say "talk at u" :-D
