Add a "conversation mode", where you set your conversation partner once ...

...and then all non-commands are sent as message to them.

/cf # rsp. /cg # sets, /cr resets target

Also reformatted display of sent group message slightly to look less beta-ish.
Then using "#<num>" for group number vs. "<num>" for friend/peer numbers.
Also changed to a slightly different message on people without name.
