Move Tab To Next/Previous Window

This script registers a pair of functions to move the current tab to the next or previous window.

You can bind it to a keystroke in Prefs > Keys by selecting the action Invoke Script Function and giving it the invocation move_current_tab_to_next_window() or move_current_tab_to_previous_window().
