Increase the number of turns a target is drawn before deletion. Now we check if a target echo is present the last three scanner turns before deletion. I've tried six turns with very good result especially for weak targets. Possible the number of turns could be adjustable.

Please consider to exclude the function when scanner range is changed, otherwise the redrawing will take longer time.

Hi
would it be possible to have an option,
that the deletion after those turns (what ever you put in 3-6?) are made gradually.....
you will create 'afterglow' the moving objects will get a tale.... 'relative your own boat' !?
just as an option ! (RM Relative Motion)

True Motion probably takes a lot more CPU-power to calculate, when targets has to be corrected
by your own speed and heading !

Rework how scanlines are 'aged'.
4aaa486 
Realised that it takes 2.5s for a full revolution of the radar scanner, so normal
minimal age is 3 (s). Add control so users can change this between 1 (for testing)
and 12 (seems plenty...)

Fixes bug #36.

Allow any number of scanlines per packet from 0 to 120.
3843fc7 
Write a log message for every packet with != 32 scanlines/spokes.

This is an attempt to be more robust.
