Smarty notice fix on Email help

Smarty notice fix on Email help

I dug around a bit on how to deal with the endless 'params' notice in full-smarty-grump-mode

I could look up the setting & permission from within the template but only wanted to do it
once per template load so I split out a help file for that field (I didn't think
a whole directory structure was warranted to I added a folder 'Help' and then the
next folder is the main help filename with the file being the help id
