More options for "Middle-click on close tab button"

[Clozent]

Description

I have been using Tree Style Tab for a while, but want to move to Sidebery. While I think Sidebery is generally better than TST, there is a feature I am missing. One of the best quality of life features TST has (through an addon[^1]) is the ability to close an entire tree by middle-clicking on a parent tab's close button.

Currently, the "Middle-click on close tab button" setting only has two options to choose from: close tab and unload tab. I propose the following additions to it:

• Close entire tree: a feature that would massively improve quality of life, saving the user from closing each tab of the tree separately.
• None: for users who don't want anything to happen when middle-clicking the close tab button.

With those options added, the setting should also be changed to a dropdown list of options, instead of the inline one it is now.
