Dongxu,

can you please have look at my forks HEAD.

I've restored the printing property for layers and added a new column for construction layer feature in layer list.
I store the construction layer property in a comment in the DXF layer table. I thought, this is the most compatible way. There is another way by extended data, DXF code 1001, for registered applications. But I'm afraid that this will lead into DXF compatibility issues with other software.

If you can agree with this solution, there are a few thing to do, but then I can merge to upstream.
