[IMP] im_livechat, mail: replace emoji with unicode.

Remove the support to replace emojis by images. Most browser
now support colored emoji or at least black and white emojis.
The emojis list have been updated to ensure a correct support
for most os/browser.
Users have the possibility to install fonts localy if their os does not
have one of the default emoji font installed.
After default os emoji font, one of twemoji, emojione or noto color
will be selected.
The emoji list is now hardcoded in js in order to reduce the number of
records in shortcodes.

Also include a small fix for livechat to display message field when rating
is bad.
