support koa ctx.state

[imsobear]

koa 文档：

ctx.state

The recommended namespace for passing information through middleware and to your frontend views.

类似 express 的 locals, 可以在 view 里直接使用的变量，如 user, 而无需每次 render 的时候都需要传入。

if (!target.hasOwnProperty(key)) {
  target[key] = source[key];
}

this.state 不应该覆盖 data

[imsobear]

额，我直接从 koa-ejs 复制的，我改下，没仔细看…

[dead-horse]

  app.context.render = function *(view, _context) {
    var context = {};
    merge(context, this.state);
    merge(context, _context);

这样吧，不改变原来的 data 对象，而且用 data 覆盖 state 的内容
