Add the ability to hide name and change display name to ig/strava handle

Hi ​@beenboston 

You can change the name displayed on your profile to whatever you are comfortable with as long as you fill in the first & last name and it follows our community guidelines. Additionally, you could also add your handle to your Personal Bio and that will be displayed on your profile page. 

• On the website, hover over your profile picture in the upper right-hand corner and click on Settings.
• Hover over the "Name" field to reveal the pencil edit icon. Complete the first and last name fields (both are required) and click Save.
• If you wish to add a bio, hover over the "Profile Bio" field to reveal the pencil edit icon. Complete the field and click Save.
