Fix router template of scaffold generator for models with name compose of more than 1 word

[tyraeltong]

One example:

rails g scaffold TestCase name:string content:string
rake db:migrate
rails g backbone:scaffold TestCase name:string content:string

the router gets generated would be like:

class AppName.Routers.TestCasesRouter extends Backbone.Router
initialize: (options) ->
@testCases = new AppName.Collections.TestCasesCollection()
@testCases.reset options.testCases
...
newTestCase: ->
@view = new AppName.Views.TestCases.NewView(collection: @test_case)
...
index: ->
@view = new AppName.Views.TestCases.IndexView(test_case: @test_case) 

While it should stick to camel name convention for js code, use testCase instead of test_case. And there're some other part of the code is using something like options.testCases but here you passed in test_case hence the problem like 'bind' is not a function on 'undefined' would happen.

I faced the same issue with multiple word model names as well. The fix mentioned here seems to work. Might be a good idea to merge this in?
