exec function for client-side javascript

[rjcorwin]

AKA Expose an exec function so other web apps can use web-terminal to run commands

Hi there - I'm building an Web App that exposes a form based GUI that runs commands via web-terminal. Much like exec in other languages, here's a client side implementation of exec that utilizes web-terminal.

Example:

exec('ls -l', function(stdout) { console.log(stdout) })

To allow isolating of the web-terminal program and a web app (web app might not want jquery mobile library), I also added the ability to run this exec function from the a parent to a web-terminal iframe. There are some restrictions to this such as needing to be on the same domain, but you can be at different ports which works for my purposes where there is an app running at domain localhost on port 80 while web-terminal is running on localhost:8080.

I also added an example. It could be cleaned up if there is a desire to accept this pull request.

Thanks R.J.

It would be nice if you update the readme file and explain the new feature.

Thanks again.

Hi Boyan. Thank you for accepting the pull request. It could definitely use some documentation, some linting (do you have one you prefer?), and there is a potential performance implication. I think the event listener here needs to be cleaned up on exit. I'll get you a second pull request sometime this week.
