Import Contacts and Contributions - Support for Multiple Option Values

Import and API users need to be able to populate multiple option values for custom fields which support them (checkbox and multi-select).

Modify the field validation and insert values code for custom fields of these two html types so that it handles a quote-delimted, comma-separated list of option values. Sample input row might look like this (the 3rd column maps to our sample GOTV Experience custom checkbox field):

Greg,Heller,"House Party,Phone Banking,Speakers Bureau",gregory@civicactions.com

Validation code needs to read through the option values in the list and validate against civicrm_custom_option values for that field.
Insert / Update code needs to insert the values with the proper internal delim character, for example: PB?PW?SB

This should be functional for Contact Import, Contrib Import (custom fields that extend Contribution), and the create and update contact API's.
