Current and laylines

Starting from iRegatta version 4.12.0 for iOS and version 3.63.0 for Android, iRegatta will also take current into the account when calculating Laylines.
You can type in current direction and speed, or you can let iRegatta detect current, if you have compass heading and speed through water as NMEA input.
