Modal for credentials

• Marked up a modal with inputs for users to enter their github
credentials in the UI
• Added FontAwesome icons for some buttons (settings button to pop back
up credentials modal)
• All hyperlinks have target=“_blank” now
Hook up the config dialog

- Moved the dialog into its own file
- Load config at the appropriate time after closing the dialog
- Made dialog fields save on blur, removed cancel button and such since
  you can't really cancel anything
