Subject: [PATCH] Fix issues related to group repeatable subsequent rows  when
 there is a checkbox or radio input. If the input is a checkbox or radio, the
 original value is needed or saving will not save the value (subsequent post
 saves work because inputs  will then have the required value set). This patch
 conditionally adds values to radios and inputs on new repeatable and sets the
 checked attribute only on the default option (radios). Fixes issue #257 (this
 will set reset text inputs as well), and #246 & #263(restores radio and
 checkbox values on new row saves)
