Only nicknames, photos, birthdays, addresses, telephone numbers, emails,
JIDs, titles, roles, notes, and URLs are supported
Due to the synopsis array not having enough space, `/vcard photo
open-self` and `/vcard photo save-self` are not documented properly in
the synopsis section of the `/vcard` command, but they are documented in
the arguments section
Fixed memory leak in vcard autocomplete (thanks to debXwoody)
Fixes https://github.com/profanity-im/profanity/issues/1649
Type `>` then press tab or shift tab to autocomplete previous messages,
then type your reply and send message.
Newlines are replaced with newline followed by `> `.
A newline is added at the end so that the user can immediately type a
message without manually adding a new line.
If re-establish a connection don't print the room history again.
In case there there happened nothing at all since we got the room
history on the last connection.
And in case there were no new messages during the time we have been
disconnected.
Instead of printing the room history again we now print 'Re-established
Connection'.
This adds a bit of overhead since we save the timestamp upon every MUC
message.
