quietly_check_login()/confirm_login() calls.  Cleans up callsites
(consisting of most of our CGIs), swapping (where appropriate) for calls
to Bugzilla->login. Patch by Teemu Mannermaa <wicked@etlicon.fi>.

Fix for bug 154008: some basic (but incomplete) maintenance on bug_email.pl, also fixes a possible security hole with a misuse
of a system() call.

bugzilla_email_append.pl calls processmail.pl after writing out the changes.

1. BugzillaEmail.pm is a (kinda, sorta) module which is going to hold the various code which is common between all the scripts which access bugzilla via email.

2. bug_email.pl uses this module

3. bugzilla_email_append.pl is a mostly ready script which will append messages to existing bugs.
