TreeView Changes (#898)

* Change to 1 click as per RFC on discord, with 100% in favour.

* Added in the ability to specify  as a view name, so it doesn't modify the title, and also fixed a bug where if you clicked *over* the amount of times your config says, it wouldn't regsiter.

* Changed plugin to use keymap.
