Set headers on Sendgrid\Email object #37

Closed jmfield2 closed 8 years ago

The headers provided to wp_mail are parsed for certain names, while others are set in a 'grand header' array and then forgotten.

It allows wp_mail and other plugins to modify the headers directly which is handy if you want to set x-smtpapi yourself for e.g. open and click tracking.

AFAICT, this patch does not interfere with any other function currently implemented in the wordpress plugin.

On second thought, this does apparently break $mail->smtpapi for other things.. I'll try to implement setFilters and PR it instead
