[geocaching] automatic naming of waypoints

[mambofive]

Hi,

while doing a multicache recently, I had an idea for a small improvement:
- when adding a waypoint to a multicache, (optionally) suggest a name for the new waypoint based on a (customizable) pattern, e.g. for pattern "WP#{0c}", create "WP01", "WP02", ...

Keep up the good work!

hi mambo,
  don't sure if customizable name is needed here ... maybe, we'll see later. Anyway I added "WPT01", "WPT02", ... suggested name ...
