FIX: t3lib_mail_Message->setFrom() does not work with "Caretaker <caretaker@domain.tld>"

setFrom() only works with plain mail addresses. Having the from address set to "Caretaker <caretaker@domain.tld>" leads to a core exception. The function setFrom() provides a second optional parameter for the senders name.

Core: Exception handler (CLI): Uncaught TYPO3 Exception: Address in mailbox given [Caretaker <caretaker@domain.tdl>] does not comply with RFC 2822, 3.6.2. | Swift_RfcComplianceException thrown in file typo3/contrib/swiftmailer/classes/Swift/Mime/Headers/MailboxHeader.php in line 309

Due to this exception no mail is sent at all.
