Add "Industry" to the company profile pages

[mwfrantz]

Add additional fields to the company records

1. Industry (comma separated list - self identified)

This should function similar to technology in terms of input - free range, comma separated.

Work required:

1. Add this field to the add/edit page for companies
2. Add this field to the company front end pages

These would eventually serve as filterable items to allow users to be able to filter the list of companies based on specific criteria.
