Goal: As an user, I want to be able to like or dislike media from the 'view' page

Note: Referring to View.aspx

Requirements:

• Source icons for thumbs up & thumbs down buttons
• • Icons should resemble the existing style (black, 2D, rounded)
• • 'Active' versions of the icons will also be required (same icon but blue in colour to indicate that icon has been clicked)
• Icons should appear next to existing 'share' and 'edit' icons
