Add commands like unload tabs (current tab or all other tabs) and split view (open in left/right and close) in Gesturefy addon.

It took me a while to figure out that Floorp specific commands at the end of Gesturefy's command list was from Floorp's end and not the add-on devs. I think it will be really convenient to have gestures to do these things. Split view is really important specifically because it isn't supported by addons like sidebery, treestyle tabs etc.
