Search improvements

Some new functionality has been added to the main trip search as well as a new search feature added on the user profile page.

The main search can now search by most trip fields, including notes, and you can select which fields you'd like to search within. As before, it will show trips from other users, but only if their privacy settings allow it or if the trip is public.

The user profile page search is intended as a quick way to find the trip you are looking for. Simply start typing the cave name, entrance or exit name, or the name of a caver on the trip and matching trips will appear instantaneously below the search box.

Hopefully this makes it easier to find and manage your data on the site.
