Expand Padrino::Cache to support all features of underlying cache

[icco]

This adds a catch all for the Redis caching class, so if you use a function in Redis (such as sets) that is not supported by Padrino, it is passed on to the base class.

I could modify this to be a little more generic, I'm just looking for a little direction.

I was thinking of adding essentially a catch all for the cache class, that could be turned on or off in the settings.

Yay? Nay?

I think this is a decent idea. Can you add a test just making sure this functionality works? Also can you change it to only pass through if the backend supports the method call (and add parenthesis to the method definition):

def method_missing(name, *args, &block)
  if @backend.respond_to?(name)
    @backend.send(*args)
  else
    super
  end
end

Cool. Test added and tweaked the function as suggested. Also synced with master.

Does this look good to you guys, affords a bit more flexibility @DAddYE
