Add filter and additional column for organization type

[dboyer]

In the program info section, orgs answer the multi-select question:

Is your organization a:

• School
• NGO or Nonprofit Organization
• University
• Corporation
• Government agency
• Other institution

This info needs to be a filter and additional column on the chapter admin page (/admin/chapters). Two things:

• [x] Add an additional column of "organization type"
• [x] Add a filter for "organization type" that works similarly to the mentor and judge type filters where the admin can select multiple choices.

Confirming that on preview I can:

• Add organization type as an additional column and if the org has multiple types, both types appear in the column
• I can use the filter to filter by org type
• Org type appears in the exported data
