LineType in a block record does not show on drawing

[JorenPelfrene]

Perhaps a similar issue as with dimensions? #556

When creating dashed lines, I find that they show correctly when added directly to doc.entities, but not as part of a block record and insert. In that case the line is plotted as continuous.
See below code example:

CadDocument doc = new CadDocument();
doc.Header.Version = ACadVersion.AC1032;
doc.Header.ShowModelSpace = true;

BlockRecord block = new BlockRecord("block1");

LineType linetype = new LineType("LTYPE:PAINT");
linetype.AddSegment(new LineType.Segment() { Length = 1});
linetype.AddSegment(new LineType.Segment() { Length = -1});

ACadSharp.Entities.Line line = new ACadSharp.Entities.Line
{
    StartPoint = new CSMath.XYZ(1, 0, 0),
    EndPoint = new CSMath.XYZ(5, 5, 0),
    LineType = linetype
};

// dashed line shows up fine when added directly to the document
//doc.Entities.Add(line);

block.Entities.Add(line);

doc.BlockRecords.Add(block);
Insert blockinsert = new Insert(block)
{
    InsertPoint = new XYZ(10, 10, 0)
};
doc.Entities.Add(blockinsert);

using (DwgWriter writer = new DwgWriter("C:/temp/acadsharp_trial.dwg", doc))
{
    writer.Write();
}

On top of that, I noticed that as soon as an insert of a block record is created on the document, also the dashed linetype of a line that is not in the insert shows as continuous.

Hi @JorenPelfrene,

Looking at your code I've found a bug in the LineType clone method, I'll open a branch to fix it.

Thanks for the report!
