Insert colons after completing nicks preceded by a list of other autocompleted nicks

When pinging two people, typing `nick1<tab> nick2<tab> message` for
autocompletion will get you `nick1: nick2 message`, which is kinda
confusing.

We only insert the colon after the first autocompleted nick,
because if a nick is used in the middle of the sentence it's mentioning
the person but not targeting the message at them.

However, this breaks down when we try to ping a list of people. There
should be a colon in front of each separating the names from the
message. only having a colon at the end of the nick list works too,
but it seems like the IRC convention is to just use multiple colons.

This patch makes it so that autocompleting a nick after a list of
existing autocompleted nicks at the beginning of the message
will include a colon.
