path_to for routes with optional parameters doesn't work

[Unitech]

By defining

map.get('/test/:p1?', 'home#test');

When I use path_to

map.pathTo.test()
// I get ''
map.pathTo.test('param1')
// I get '/test/param1?'

---

A cool feature would be to declare route parameters like that :

map.get('/test/:p1/:p2?', 'home#test');

And to map them like that :

map.pathTo.test({p1 : 'param1', p2 : 'param2'})

Anyway thanks for this very nice piece of code
