Breaks in multi-line address routes

Add breaks in #show for multi-line address routes. Simple solution was
to join the address fields with newlines then use simple_format to
filter result.
Company delete button on edit page

Added delete button to company#edit.
Update people search when company name changed or deleted

We are caching the company name and id in the person elasticsearch
index. This allows faster listings without n+1 queries. After a company
name is changed or the company is deleted, we need to force
elasticsearch to reindex the company.people. We do this by calling
update_elasticsearch_index in a callback.

Unfortunately, dependent: :nullify doesn't do any callbacks. We had to
manually nullify the company_id in company.people and then force a
reindex by elasticsearch.
New, improved favicon

Loy Moser created new favicon using lowercase r and uppercase t to make
a 'round table'.
Address mark added to search index

Missing "mark" added to to_indexed_json to allow scoping address
searches by elasticsearch.
