Copy time and users name when copy paste conversation.

As far as I can se this was removed due to the fact that some people copy paste code directly into production system where time and usernames caused problems.

However in the normal world it not to uncommon to quote, even between organisations or even mail.
And then you REALLY REALLY need to have time and user name.

This was also what was default until recently, and currently everyone is sending screenshots, something that ofcourse is not a good solution.

In order to make everyone happy, make an option in settings to not copy username/time and make it unset as default, those who need it will find it for sure, the rest will get the expected "what you mark is what you copy" behavior.
