Script Summary: Logs you in automatically to Trac: sends you to the log-in page and submits the log-in form if Firefox has prepopulated it. Rationale: Tracs easily forget your session, which gets annoying.
Assumes an AccountManager-like authorization system as seen on e.g. DevjaVu.com and dev.rubyonrails.com.
If you're sent to the log-in page and the form is not populated by Firefox, you'll be sent back. In that case, and if you log out manually, autologin is disabled for the site in question until the browser is restarted or the login page loaded.
