Add quick emoji button next to text input

This allows for a user selectable button to be displayed
next to the SMS text input area to allow quick access to the
emoji icons. Seeing as how the current process to add an emoj
requires going through the menu and then selecting the option,
this allows for frequent users of emojis a much simpler and time saving method.

Big big thank too Roman Birg.
