RFR 8133948: Add 'edit' function to allow external editing of scripts

[Sundararajan Athijegannathan]

Hi,

Please review the updated webrev (in place).

http://cr.openjdk.java.net/~sundar/8133948/

I tested this on Windows with external editors being notepad.exe, 
gvim.exe and internal editor.Thanks to Hannes for testing it on Ubuntu.

As I mentioned earlier EditPad and ExternalEditor are cloned from Kulla 
project and modified to suit nashorn shell requirements. We can revisit 
and refactor code to jdk.internal.le module later.

Thanks,
-Sundar
