Better implementation of inline emojis

Problem

Most gitlab text inputs support html markup and fancy features such as inserting emojis 🎉

Adding an emoji inline is not a great experience as you have to know the code which you're planning on using. i.e. If I wanted to create a smiling emoji I would need to know the markup for that is :smile:. Handling emojis this way doesn't allow for easy access to viewing and selecting emojis when they are needed.

Solution

Create a better inline emojis tool - similar to the one used for replying on comments
