Center Window Ignoring Splits (run again to restore position)

Description
Moves active window to center of monitor, overriding splits. When run again restores original position.
Position is stored per window, so any number of windows may be centered and then moved back to original position.
Set targetWidth to change window's width when centered (width is also restored when restoring position).
TIP: set targetWidth to 1920 to emulate the width of a borderless Full-HD window (very useful for ultra wides)
