Create separate "Trip Details" form

[maplethorpej]

Right now, a pack and the trip details are basically the same entity. We could break these out so that the "Trip Details" gets a separate page and form, and then packing lists can be assigned to it. Some users mention that they use multiple packs per trip.

The other advantage is that this would make the trip details less of an afterthought and encourage users to add more info about a trip.
