Move Tab To 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
- if the tab is in a tab group, when moving it the identical group will be created or used in another window. When moving back to original window the tab will return into its original group
- 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 there is only 1 window, a new window will be opened on move
- keyboard shortcut support
