Fix matching routes with trailing slash (refs #532)

Hi,

It's an attempt to fix non-functioning routes when using trailing slash. I stumbled upon it while testing my app with urls like http://app-domain.dev/recipes vs http://app-domain.dev/recipes/, where in the latter case Chaplin doesn't recognise my routes anymore.

My `routes.js.coffee`:
```coffeescript
define ->
  'use strict'

  (match) ->

    # ... snip ...

    match 'recipes',          'recipes#index', name: 'recipes'
    match 'recipes/new',      'recipes#new',   name: 'new_recipe'
    match 'recipes/:id',      'recipes#show',  name: 'recipe'
    match 'recipes/:id/edit', 'recipes#edit',  name: 'edit_recipe'

    # ... snip ...
```
