added query string support

[arisAlexis]

I wanted support for this in my project to make the logic a bit closer to express for example so that there is a req.query object with passed in parameters in the url. I didn't want the order of the parameters to matter for some routes and also including stuff like a token in a route param feels better in a query string.

I made sure all tests pass and added a new test. (it works side by side with named params).

Atom removed some trailing spaces automatically idk if you want to keep them.

Also, this is my first pull request ever , hope it was helpful :)

@gopeter dirty fix I am using right now

you add it as middleware this._router.add('search/:query',this._getQuery,(req)=>new SearchView({data:{query:req.query}}));

then then use this function

_getQuery(req,event,next) { req.query={}; let queryString=req.params.query.replace('?',''); queryString.split('&').forEach((q)=>{ const name=q.split('=')[0]; let value=q.split('=')[1]; if (value==='true' || value==='false') { req.query[name]=JSON.parse(${value}); } else { req.query[name]=JSON.parse("${value}"); } }); next(); }

so in effect you only put a slash and use the query as a parameter and you get a req.query object

Github reports of conflicts but I am not sure if this will ever be merged.
