handling for custom form fields

[stmichael]

In our forms we have a bunch of special autocompletion fields which do not conform with the implementation for the standard autocompletion field. So corner_stones doesn't work with them.

It would be nice to have a mechanism to provide custom field handlers like:

CornerStones::Form::FieldSelector.add_field_handler(custom_autocompleter)

Or with a config like mechanism:

CornerStones::Form.config do |c|
  c.add_field_handler(custom_autocompleter)
end

corner_stones should check the custom field handlers before the general handlers provided by itself because the custom fields are always subsets of the general handlers.

sounds like a reasonable feature. I'll have a look at it.
