Small fixes after ORP

[sprintf]

1. add timestamps to the lap logger file ... this will allow us to see when we do pitstops and determine how long our stints are from a time perspective
2. disable the fuel panel showing up ... we want the race position info to show up as the line is crossed
3. disable setting time via GPS ... just trust GPS, and know wifi time is good enough
4. dial down the "INFO sending message to pit" messages ... they are too much on every ping
5. dial down the "INFO predicted lap time" to every 20s or so.
6. tell us the gate number on the predicted lap timer log
7. why no pit entry (LeaveTrack) line cross events?
