LDPartEditor 0.8.39-beta

Changes:
With the release of 0.8.39 you are able to...

• ...use a SlantingMatrixProjector tool.
• ...save all your user settings in a file, and restore it when you want to (screenshot).
• ...restore your 3D view settings when you completed a PartReview.
• ...use ALT + UP/DOWN to move a line up and down in the text editor.
• ...see a progress bar when downloading files from the PT for PartReview.
• ...set the coplanarity threshold (Tools... -> Options...).

The following critical issues are fixed:

1. Colour palette: The window was sometimes not wide enough.
2. Sometimes long edges were hard to select until both vertices were visible.
3. The logger did not detect errors while loading the workbench.
4. An edge, or cond-line was selectable through a surface, even if it was hidden behind that surface.
5. Ytruder generated triangles when it should generate quads.
6. "Save As..." created a wrong part type (Flexible_Section).
7. Divide by zero during Catmull-Clark subdivision
