Do not open links in new window ;-/
Use contact form's recipient address for smtp from header
Use checkmark for list image style on home page
Use redis session store for production setup

This resolves the warning message issued upon web app startup:

"Warning: connect.session() MemoryStore is not designed for a production
environment, as it will leak memory, and will not scale past a single
process."
Bit of clean up in lib/form_helpers.js

* Remove or disable (comment) un-used variables,
functions.

* When errors, log regardless of app
environment.

* Fix the generated email's FROM field.

* Add an err check for when the JSON response
message is not 'success'.
Append 'novalidate' to contact form if not in production env
