geth js stopped the JS runtime after running the first input file
and blocked for pending callbacks. This commit makes it process
all files and enables quitting with Ctrl-C regardless of callbacks.
Error reporting is also improved. If a script fails to load, the error
is printed and includes the backtrace. package jsre now ensures that
otto is aware of the filename, the backtrace will contain them.
Before:
$ geth js bad.js; echo "exit $?"
... log messages ...
exit 0
After:
$ geth js bad.js; echo "exit $?"
... log messages ...
