Move Tab to Next Window ruma Roman Shevtsov

Adds a tab context menu item and a button action to move a tab to the next window.

Especially useful for these amazing multi-monitor setups when it's too annoying to drag tabs around between windows.

## Quick feature list

- the source tab position is saved in all windows, so if it's moved back into a window, it moves into its original position
- multiple tabs move - select multiple tabs (use shift or cmd/ctrl) and move all of them into the next window in the same order
- if the tab is active, it will become active in the new window
- if the tab is inactive, it will stay inactive in the new window
- if there is only 1 window, a new window will be opened on move
- keyboard shortcut support
