Set timeout

[Nanonid]

#28 Simple example of setTimeout. My pull adds the unfortunate CharkaCore.dll for those who don't build it. This pull also uses .net 3.5, so is more for reference.

Thanks @Nanonid! We did have a settimeout implementation in a C++ sample, but one for .NET would certainly be useful and I like the idea of adding a proper .gitignore. @Yongqu would you mind taking a look at this?

Please add a note indicating that return value cannot be used as cookie for clearTimeout.
It would be nice if we can hide the dt as getter/setter.

Hello everyone,

I think setTimeout is a bit outside of scope for ChakraCore.
It's usually implemented on the browser engine.

What do you think?

[liminzhu]

@Kureev you're absolutely right that setTimeout is a Web API and is outside the scope of JavaScript. It is supplemented by the host (browser, Node, etc) and that's why ChakraCore doesn't support that right out of the box. That said, it's an useful function (another example is console.log) for many hosts, therefore I can see providing an example implementation in the host sample as helpful.
