Yahrtzeit more accessible

Improvement: A change on how you can view deceased members and modify Yahrzeit information.
Here is a summary of these improvements.
1. Deceased family members are now separated and appear below other family members in their own section.
2. If there is yahrtzeit info, it will be displayed in this section as well.
3. A "Y" button allows you to directly edit and add yahrtzeit info to any deceased person.
4. When viewing an member page, a list of all Yahrtzeits for that person is displayed.
