Patch: Improved stock emoji keyboard

This patch adds more emoji characters to the stock emoji keyboard layout. In its current state, a new line is added and a second page is available. The second page ("shift") will be filled with new emojis as needed.

If you want a certain emoji to be included, feel free to ask in the comments.
