[CI 1.7+] Email Class - useragent not configurable

[eluser]sophistry[/eluser]
yes, i just hit this bug too - consider it verified. i have posted it in the bug tracker here:

http://codeigniter.com/bug_tracker/bug/6643/

this is how i fixed it - not sure if it is a long-term fix, but it let me set the User-Agent header in my email.

around line 922 in the _build_headers() function you'll see a list of _set_header calls, add this one.

Code:

$this->_set_header('User-Agent', $this->useragent);
