1.0.3: bug fixes + accept/reject logic

bug fixes:
RecordDetailFragment: removed ‘Record created by’. Was not loading and
was causing an error
RecordListFragment: populateList() onAttach() so Activity != null
RecordListFragment: onActivityResult, removing record throws NPE,
checking to make sure adapter and record != null

Accept/Reject logic: If status_by = user, no accept/reject option. If
status is accept or reject, hide buttons
