[mkgmap-dev] Commit: r2759: Use shifted offsets in LBL so that more labels can be saved.

Version 2759 was committed by steve on Wed, 16 Oct 2013 Use shifted offsets in LBL so that more labels can be saved. Labels are now stored with offset/2 so that you can hold twice as many labels as previously. There is also a proper check for overflowing the LBL section.
