lasso/middleware & koa v2

https://github.com/koajs/koa

I peeked in the middleware.js file and see that it's been made to comply with express. I tweaked my own version and is working. Just want you to know this!

working for koa (lasso/middleware/serveStatic.js):

    // line 44
    return function(ctx, next) {
        var req = ctx.request,
            res = ctx.response;

In koa ctx is passed instead of express' req and res.

Currently:

module.js:471
    throw err;
    ^

Error: Cannot find module 'lasso/middleware/koa'

I've fully fixed this now, tested on both koa and koa@2. Here is the pull request.

Currently fixing the send module so that it works with both versions of koa, once that is fixed I'll update lasso.
