New icon for deleting a Cheep

This new icon is using the Font Awesome library that we are already using. The primary reason for this change is:

Faster Loading: Icons are loaded from a single CSS/JS file, improving page load times.
Less HTTP Requests: Reduces HTTP requests by using one font file for all icons.
Easy Change: Icons can be easily swapped or modified through CSS.
