FS#1289 - Spline from fit points: load error for non-periodic but closed splines

After saving an open designed Spline QCad will open it the next time as a closed spline.
Trying to fix this in the Property Manager using “Closed Periodic yes/no” leads to an open but broken spline.

Pic 1 = designed
Pic 2 = saved/opened from HD
Pic 3 = Try to fix this with the Property Manager

Reason for closing:  Fixed
Additional comments about closing:  

Fixed by guessing that a spline is periodic if its start and end tangents are not 0,0 and equal. This should cover the most common cases.

Unfortunately, open splines with start point == end point and closed periodic splines are stored almost identically in DXF/DWG. The only difference are the start and end tangents which are currently not supported by QCAD.

One possible work around would be to introduce a minuscule distance between the first and last fit point (e.g. 0.000001).

Good to know - thanks Andrew. ;-)
