- Highlights and encryption icons are now supported.
- Some other hacking up of the textview code was done, removing more of the old
  code.
- The new textview got support for adding history messages!
- ChatControlBase can now fetch and stuff in history into the textview, whilst
  maintaining scroll position.
- Scrolling back in the textview results in history getting dynamically loaded!
- In addition, we now load 100 lines of history for each chat view when it's
  first opened.
