The "Mass Mail Users" functionality has an option to add a Suffix before the Subject, and some Mailbody Suffix to the end of the mail. You can configure that via Users > Mass Mail > [Options] > [Mass Mail].
Summary of Changes
This PR adds the optional default Subject Prefix and Mailbody Suffix to the view of the Mass Mail form so that it is clear if, and what, Joomla will add to the mass mail.
Testing Instructions
Before the PR:
backend: Users > Mass Mail (Users) > [Options]
Configure some Subject + Mailbody suffix.
Go to the Mass Mail form:
Users > Mass Mail (Users)
After the PR:
Go to the Mass Mail form: Users > Mass Mail (Users)
It should show the configured Subject Suffix before the Subject field,
and the configured Mailbody Suffix below the Mail Text field.
