button_to fails csrf

[robacarp]

The button_to method has no way of passing in a csrf, nor does it render one, so it always fails CSRF check.

This should work

button_to("Save", "/save", :delete) do
  csrf_tag
end

Or maybe use some js for that, just like rails

@infernalmaster This was actually what was done. Please see: https://github.com/amberframework/amber/blob/master/src/amber/cli/templates/scaffold/view/src/views/%7B%7Bname%7D%7D/index.slang.ecr#L24
