eq_visit table needs to be updated

[apippin]

• A new "type" field should be added to the eq_visit table with enumerated values "hometeaching" and "presidency".
  • The upgrade script should set all visits currently marked as companionship=0 with "type" "presidency" and all other visits should set to "hometeaching".
• Add 2 new fields to the eq_visit table to accomodate "custom" companionship visits (presidency visits for example). Call these fields "elder1" and "elder2".
  • The upgrade script should add these new fields and default their values to NULL.

I called these fields companion1 and companion2 so it isn't tied in to the EQ.
