This commit adds emojis to base SmsWidget in order to use a text field with
both sms and emoji widgets in "mass_mailing_sms" module for sms content.
The emoji feature is optional (depends on "enable_emojis" attribute). To add
the emoji support, the following changes have been made:
* override the method "on_attach_callback" from emoji widget base code to
hide emojis if not enabled;
We also adjust the css of emoji widget to make it suitable for a text field
with sms option.
