Basic emailng setup
2 day notification

Made the two days left notification email take precedence over the 5
days after email. No emails will be sent outside the opening and
closing dates.
Notification email
More tables, better trips

Made the bio:email thing respond to errors better. Made lots of tables
to display data. Fixed bug where you could attempt to evaluate a trip
even if you already had evaluated it. Also implemented the global
variable closing time.
Gitignore, readme

Added gitignore files so that app/cache, app/logs, and web/files would
not be included in version control.
