Allow referencing other apps (#692)

- [x] Update chat_stream_handlers
- [x] Update token handlers
- [x] Update HomeChatInput
- [x] update lexical chat input: do not allow referencing same app
(current app, or other already selected apps)
- [x] I don't think smart context will work on this...
- [x] Enter doesn't clear...
