Releases for User Email text format

Re-release of 1.4, tagging failed somehow.

"Fixes fields with checkbox not being transformed."

The last approach required to store the user_mail config as an array [value, format]. and it required a lot more effort to return the config. It also resulted in a warning from 'user' module as the module tried to process tokens.

Now the 'text_format' field format is concatenated with the field value, so the user module can proccess the token for us and no more warnings from 'user' module.

fix composer.json sintax and mail_alter only messages sent from module 'user' in order to avoid conflic with 'update' and others.
