Title: Support symbol and string actions in AC#respond_to options

``` ruby
class HomeController < ApplicationController
before_filter :some, :only => [:aaa, 'bbb'] # Works well
respond_to :xml, :only => [:aaa, 'bbb'] # <-- Should also work

def aaa
respond_with :aaa => 3
end

def bbb
respond_with :bbb => 3
end

private
def some
# ...
end
end
```
