Title: Also parse params when no description is given

Something that was bothering me for a while now: if no description is given, the params would not be evaluated, so
```` ruby
params do
requires :one_param, :desc => "one param"
end
get "method" do ; end
````
would do nothing, you would need to do
```` ruby
desc 'some description to make the below work'
params do
requires :one_param, :desc => "one param"
end
get "method" do ; end
````
