RFR 8087292: nashorn should have a "fail-fast" option for scripting, analog to bash "set -e"

[Sundararajan Athijegannathan]

Updated webrev: http://cr.openjdk.java.net/~sundar/8087292/webrev.01/

Updates:

* Added throwOnError property (false default) to $EXEC function object
* Added a test case (suggested by Michael offline)

On RangeError: I interpreted as { 0 } as only "expected" set of exit 
code values. Anything outside that is a "range error" as /RangeError/ 
object indicates an error when a value is not in the set or range of 
allowed values

Thanks,
