Merge branch 'devel' into feature/contact-email-template
Update formating (2 spaces), remove comment, fix image sizes
Minor tweaks to improve email readability
Let email defaults take over, reduce config overhead

Fix two things:
- the reply-to is already being set to myusa@gsa.gov by
  the action mailer defaults
- emails for notifications should NOT come from
  no-reply@[app_domain]
  Instead they should come from the default myusa address
  no-reply@[myusa_host]

This commit fixes these items.
