[Feature Request] Quick button to turn last seen and online on/off

[syswraith]

Traditionally this switch is buried in
Settings > Privacy and Security > Privacy > Last Seen and Online
and it allows read time to be toggled on/off as well, but it would be really good to have this as a toggle on a contact's profile page OR three dots menu in the chat.

This would eliminate the need to add exceptions manually by having to go into Settings every time.
