Added more social media icons and corrections

Description

I've added more social media icons like Gmail and Bitbucket and have changed the body size to fit the icons properly. I've changed the color of each icon according to the most appropriate official color code. I've also changed the listing of accounts in edit.html according to the icons listing in popup.html.
