PURPOSE
Allow to use the text field with integrated emojis support in other apps
notably mass mailing
SPECIFICATIONS
Currently there is one emojis enabled widget which is based on text widget.
It is therefore limited to ``<textarea/>``.
In this commit we propose to support emojis in char fields, aka using an
``<input/>``.
We therefore move most of the code within a ``FieldEmojiCommon`` and then
creates two widgets based on it
* ``text_emojis`` inherits from ``FieldText``
* ``char_emojis`` inherits from ``FieldChar``
