Documentation: describe trips in the dive list

Both autogroup and manual creation of trips is explained. Once the user
looks at manual creation, the other trip manipulation options should be
fairly self-explanatory.

+An innovative feature in Subsurface is the ability to group dives by
+"trips". What this means is that multiple dives can be categorized
+together under a common header. Typically this is used by divers who
+travel for a limited time to a dive destiation - the location in the
+trip header can then be used for the destination information
+("Phillippines, Puerto Galera"), while the location in the individual
+dive can describe the actual dive site ("Hole in the wall").
+
+Subsurface usually does a very good job detecting and grouping dive
+trips together. To use this feature simply enable the "Autogroup"
+option in the "Log" menu entry. Alternatively, you can select multiple
+dives in the dive list and use the context menu (right click on one of
+the selected dives) to create a trip. The context menu contains
+several additional options to allow manipulation of trips - these
+should be self-explanatory.
