Add autogen menu command

Browse source 
This adds the ability to auto create trips from the menu. It's a toggle
entry (and while at it, we made the zoom toggle a toggle entry as well).
We can therfore switch back and forth between auto generated trips.

There is one bug. Assume you have no trips. You manually create a trip
from some dives out of a group of trips that autogen would turn into a
trip. Now you turn on autogen and this trip gets expanded with all the
dives that would normally be grouped together. If you turn off autogen
again, all those dives are still part of the remaining (initially manually
created) trip. Working around this issue seemed a lot more work than the
likelihood of anyone running into it seemed worth.
