Custom fields are NOT being saved for some component custom data (activities, membership ...)

Saving custom field data for many component objects seems to be completely broken in master right now.

Retesting this as of 4.7 alpha (Sept 27 latest checkout) - the following component custom fields do NOT save values:

• Activities (tested by type = Meeting)
• Membership
• Relationships (tested by type = Employee / Employer)
• Campaign (tested 'any' type)
• Grant (tested by type = Emergency)
• Cases (tested 'any' type) *** This does NOT work from 'Add Case' form, but DOES work from Manage Case - edit custom field pop-up form.

These entities ARE working:

• Contribution custom fields (any AND by type) work properly
• Event custom fields (tested "by type") works as well
• Groups custom fields

To recreate -

• Add a new contribution and set a value for one of the Donor Information fields
• View the contribution - no value is set
• Check the civicrm_value_donor_information table - no record has been inserted

Same thing with membership custom data (haven't tested other entities).
