Change long press behaviour for tabs

[msfjarvis]

The long press action seems to create a dialog that simply shows the name of the tab. I personally find it to be a waste of precious contextual space, and instead would like to suggest repurposing it as a delete action, with a confirmation dialog or an undo UI flow, whatever feels more natural to you.

Thanks for the suggestion! Long pressing it will probably be used to reorder the columns.

#80 was started but it was not cross-platform so it was not merged. Pull Requests welcome!

I'm a native Android developer, React and Typescript are still not part of my skill set so I'll just wait for someone capable of executing this to drop by :)

Closing in favor of #42. Also on v0.95.0. this alert was removed.
