Support for MTK-based logger .bin files
I've fixed a bug in GPSLog Labs that was preventing binary files from MTK based loggers from being processed properly.
The MTK chipset is used by the Transystem i-Blue 747, Qstarz BT-Q1000 and others (see http://bt747.org/compatible_gps for a list.)
This will hopefully streamline the workflow for a lot of people as it will no longer be necessary to convert to GPX format before uploading and the .bin files are much smaller than the equivalent .gpx.
