	Load Tab in New Window 1.0 by Jim DeVona

	19 December 2006
	
	Close the frontmost Safari tab and reload it in a new window.
	
	Requirements:
		UI Scripting
		Developed with Safari 2.0.4 on Mac OS X 10.4.8
	
	Suggested installation location:
		~/Library/Scripts/Applications/Safari/
	
	You can invoke this script with the standard Mac OS X Script Menu
	or any one of many excellent third party utilities that allow
	keyboard shortcuts to be assigned to scripts.
	
	Issues:
		- UI scripting in close_tab() often hangs on my G4;
		  too bad Safari's tabs weren't scritable directly:
		  http://daringfireball.net/2003/05/safaris_unscriptable_tabs.html
		- Ideally the page would just be "moved" to a new window
		  without reloading it.
