LDPartEditor 0.8.5-beta

Changes:
With the release of 0.8.5 you are able to...

• ...use up to 9 decimal places for rounding (coordinates + matrix).
• ...open the part in the 3D editor from the text editor window (orange "3D" button)
• ...benefit from a new "how-to-use" description for the SlicerPro2 tool.
• ...use "save as..." to store files under a new filename (text editor only)
• ...use a button for single vertex manipulation ("SyncEdit") in the text editor.

The following critical issues are fixed:

1. Rectifier created rect#.dat primitives when "Split" and "Slicerpro" were used.
2. The internal Rectifier created rect-prims that were scaled in three dimensions.
3. Fixed an issue which was related to the parsing of the !HISTORY meta command
4. Fixed a null pointer issue with "Add Quad" and other "Add..." functions.
5. Fixed incorrect cursor movement when single vertex manipulation was active.
6. Fixed a GUI access issue, which occured on drag&drop with text editor tabs.
7. Fixed a random null pointer issue, which could disable the tab from the text editor window when more than one tab was opened.
8. In some rare cases when a flat subfile was scaled in X/Y or Z and the transformation matrix contained more than one space as seperator between the values, the corresponding "Quick Fix" was not able fix the scaling.
