Add ability to change image with other info

- Modify the edit page to allow users to change their image at the same
time as changing other information, and only have to submit once.
- Add code to display any image uploading failures to the profile page
- Minor modifications to fix typos that IE was complaining about.
Changed styling for HQ phone list download button to blue.
Add email notifications for directory updates

- Added php-based email notifications to the hr admin team whenever a
user updates their address in the staff directory.
- Also fixed minor javascript-based issue related to changes in the
image uploading system.
- NOTE: As part of this change, the system will, by default, send
emails to the hradmin team, unless a constant is defined in the
web-config.php file for wordpress. I have added this constant to the
web-config for the dev site.
Add a note for timeline of syncing

Add a note to the email notification to let users know that it might
take a bit to see changes from staff directory propagate to HRIS and
StudioEnterprise.
Merge branch 'dev'
- Modify staff directory updating to have the ability to update image along with
  other info at the same time.
