Goal: As an user, I want to be able to like or dislike media as I scroll through an media_tag collection

Note: Media_tag collections use MediaControl.aspx to display individual media items. This is where the like / dislike controls need to be added

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
