Added a JS command that will run javascript outside of Dosbox

[thijsk]

I created a new "dos" command that will execute the javascript in the file specified as the argument to the command.

Example:
c:>JS myscript.js
will execute the script in the browser

Usefull for building a batch file that can execute javascript commands

Any thoughts/ideas/tips?

This is interesting and it works, but is it actually useful?

I was experimenting with .bat files that can influence the look of the page that the dosbox.js is running on. So it's kind of usefull in that way.
I used the setTimeout in an attempt to prevent the dosbox from crashing when the javascript executed by "JS.COM" was invalid; that didn't really work so the workaround is to keep the executed js as simple as possible, which is not really a good solution.

I think it makes more sense to give JavaScript access to DOSBox than to give DOSBox access to JavaScript. Settings might be more convenient via JavaScript than via a dosbox.conf file. Maybe it would be useful if JavaScript could perform actions like simulating key presses, running commands, and waiting for events.
