Redmine

I submit this rather elementary patch that fixes 2 issues in mail_handler.rb:

1) If Project: tag in email cannot be honored (missing project), rather than failing, the issue is assigned to the default project defined in settings

2) Preserve outlook style email addresses in the form <user@domain>. Previously they were stripped as html tags because the <> brackets. The regexp is rather liberal but I find, well suited for the job.

Patch is against Redmine 2.0
