Add option for starting a direct messsage on detail menu

[tigexplorer]

Describe

If a profile is shown, it has a details button with some options, like "Open in Browser", "Mute" etc.

Why

For starting a direkt message, one have to manually type or copy/paste the handle in the message box. It would be nice, to have in the details button/ menu the option to start a direkt message.
