1648	[PATCH] NMEA parser improvement	anonymous	framm	"Patch is against currnet SVN. Ignore 3 leading path name segments to apply.

Improvements to the NMEA parser:

- evaluate checksum, drop bad sentences

- parse additional data such as speed, course, elevation, fix, dilution

- drop malformed sentences instead of throwing an error

- drop sentences with zero coordinates

- Evaluate GGA sentences too so the screen won't stay blank if the device does not write RMC sentences

- show a message box with conversion stats (number of good coordinates, malformed sentences, checksum errors, unknown sentences, zero coordinates) at the end

- don't create an empty layer

Remaining things:

- midnight overflow in NMEA data can cause time inconsistencies if the device writes both GGA and RMC sentences

- a import options dialog might get handy (to enter date for GGA-only data and maybe some filtering options)"	enhancement	closed	major		Core		duplicate	NMEA log import
