On the Mailing report pages, custom reply-to address display format is broken

When creating a new mailing, there is an option to provide a custom "Reply-to" address (if enabled under Mailing Settings). The options for the "Reply-To" address are the same as the options for the FROM address, which are set on Administer -> CiviMail -> From Email addresses page. These addresses MUST be in a format with quotes around the name and greater than / less than symbols such as : "name of sender" <name@domain.org> or "name of sender" <name@domain.org> around the email address.

When it comes to the mailing report, however, these look like normal html tags, and are interpreted as such by the browser- so the address comes out with just them name : "name of sender" the email address itself is inside the tag, hidden.

Easy fix with CRM/Mailing/Page/Report.tpl by adding the smarty |htmlentities function:

{$report.mailing.replyto_email|htmlentities}

I also removed the < and > around the reply-to email here, since it is already present.

I am rolling a very simple patch, and will attach it here when I have it ready.
