Custom Data - Extend Activity, Phonecall, Meeting, Group and Contribution Classes

1. Custom Groups may 'extend' Activity, Phonecall, Meeting, Group and Contribution Classes (in addition to existing options to extend Contact, Individual....Location...).

NOTE: Contribution is a new class - schema has been implemented in trunk.

1.1 Add/Edit Custom Group (uf/group)
-Modify 'Used for' (extends) select values to include new options
Change ' all contact types -' default label to 'All Contacts'

• Display Style is always 'Inline' for groups which do NOT extend All Contacts or one of the contact types

1.2 Data values are stored in civicrm_custom_value with appropriate entries for entity_table (civicrm_contribution, civicrm_activity, etc.) and entity_id (PK of associated gift or activity).

1.3 All defined custom groups are included as fieldsets in the Add/Edit Form and View for the applicable class (handled the same as Inline groups for Contacts)

2. Profiles (UF_Group) may now include core and custom fields belonging to different classes
2.1 Add/Edit Profile Field (uf/group/field) - CiviCRM Field Name drop-down (civicrm_uf_field.field_name) includes all core fields for contact, activity, meeting, phonecall and contribution, AND all enabled custom fields - regardless of which class they extend. For readability, we should group the fields by class and use null separator options:

• Contact Fields -
  First Name
  ...
• Custom Contact Fields -
  Marital Status
  ...
• Activity Fields -
  Subject
  Scheduled Date
  ...
• Custom Activity Fields -
  Foobar
  (etc.)

2.2 Modify Profile form processing code so that it can handle insert or update of multiple objects/classes from the same form (e.g. insert a new contact AND an activity or contribution record)
