Super Powerful Routes 

This PR introduces a huge improvement in our routes making it easy to define different callbacks for each path. Below I am adding some examples, check the tests for more details.

```javascript
// Defining several routes at once
riot.route({
   // static route
   "/home":  function(params) { ... },
   
   // RegEx route 
   ".*/something": function(params) { ... }, 

   // Passing params
   "/items/{item}": function(params) { ... },

   // With RegEx and several params 
   ".*/{type}/{id}?.*q={q}.*": function(params) { ... }
});

// Defining a single route
riot.route("/somepage", function(params) { ... });

// Trigger a route, this will execute the the callback of this route
riot.route("/somepage");
```
this tests the route mapping
