Fix https://github.com/gregbell/active_admin/issues/1999: translation_missing error
Add :allow_destroy option to has_many forms

This option will add a boolean field "Remove"
to the end of each has_many fieldset that is
an existing record. This provides a workaround
for issue #1990, and allows for cleaner form
coding.
