Clicking delete prompts warning

[ari-os310]

The way the delete function is set up right now, someone could accidentally delete an affirmation without first being prompted to confirm. Clicking delete should prompt either an alert or a modal box prompting confirmation of delete action.

This issue intends to:

• create a modal or alert that asks "Say goodbye to affirmation forever?"

• Clicking "x" on the affirmation will prompt modal/alert verification

• Selecting yes will continue with the deletion

• Selecting no will disappear the alert or modal and do nothing

The delete function currently lives in file AvatarPage.js on lines 19-21.

The delete function is passed down to AffirmationsList.js where it is called.

As written in moodify-db-helpers.js, it takes two parameters when called:

1. affirmation id

2. function call back
