send-cmd should prepend last arg with : only if /\s/ (#58)

* send-cmd should prepend last arg with : only if /\s/

ideally according to the IRC specifications, `:` is optional if the last argument to a command has no whitespace

This is to help alleviate some difficulties in zoffixznet/perl6-banbot#2

I am not completely sure all servers agree with the IRC specification on `:` however! Hopefully this is safe enough change to make

* send-cmd should prepend : if last arg has ^':'

* changing last-arg of send-cmd handling to support RFC

situations where a colon `:` needs to proceed the last argument:

* the last argument is the empty string `''`
* the last argument has a space `' '` in it
* the last argument begins with a colon `:`

Otherwise, other than PRIVMSG | NOTICE, some servers expect there to not be a colon to denote the last argument in some commands
