reworked: adding parameter to all mail options

I started over from scratch.  The new parameter additional_recipients is
now added to the mail options parameter in each XML file that includes
these parameters.  Also added always_copy_to parameter to the global
config.xml.

[#30151] - added multiple validation

Each of the added fields now include validation, and the "multiple"
attribute allows for comma separated values (each to be validated).
