fix for supporting custom input types (eg address)

if resource is not supplied, do not wrap the fields in request hash
remove obsolete files since update to 1.4
update src to 1.4 +
add params = null when params is empty to support
rails style empty checkboxes. Simulates the hidden field tags
set default datatype to 'script', gives the ability 
to return javascript
