Add option to disable showing parent posts in replies

[hloeung]

Hi,

When someone replies to a post, matterircd shows this in https://github.com/42wim/matterircd/blob/master/mm-go-irckit/mmuser.go#L303

On IRC, it looks something like this:

|15:46 Thanks @bob_user2 ! |15:47 no worries :) (re @jane_user1: Thanks @bob_user2 !)

With extra/duplication. Can we have the option to disable this? Perhaps via the config file so it's not the default behaviour.
