When creating users from emails with internationalized From-headers, fullname is not unquoted.

The following email, passed to rdm-mailhandler.rb (with appropriate --url, --key, --project, --tracker, --no-permission-check options and --unknown-user=create)

From: =?utf-8?b?w4TDpCDDlsO2?= 
Subject: foo
Content-Type: text/plain; charset=utf-8

testing user creation with quoted From-header

creates a user whose fullname is set to '=?utf-8?b?w4TDpCDDlsO2?= -', when it should in fact be set to "Ää Öö".

The attached patch based on the 1.3-stable branch (svn r8910) fixes this issue.

(It's possible this is actually a bug in TMail (which is what Rails 2 uses), but that doesn't seem to be maintained anymore; the last release and latest mail sent to its mailing list were in 2010.)
