Downcase hidden methods in RESTful example

Browse source 
- this documentation is mildly confusing when combined with hiccup's
  `form-to` since hiccup forcibly transforms the method specified in
  its convenience syntax: `(form-to [:delete "/my-url"] ... )` into an
  upper-case string:
  80e48352dd/src/hiccup/form.clj (L130)

- it's also common to get an upper-case string from elsewhere so it
  seems best to wrap the hidden `_method` in `lower-case`.
