GUI updated to support display scale settings 125% to 200%
Access display settings by right clicking on the desktop then selecting "Display Settings".
In the section "Scale & layout" is the "Scale" setting. This changes the size of text, apps and other items.
SusProg3D now fully supports all settings: 100%, 125%, 150%, 175% and 200%.

Corrected the live axle chassis and links input dialogs that defaulted all values to zero.
Corrected the coil spring input dialog to save the opposite side spring when symmetric.
Thanks to Luke and Damian for these.

The registration form was missing the Request button. Fixed.

If the coil spring data was invalid then the spring dialog would hang (attempting to draw an infinite spring).
Now, if the coil spring data data is invalid then the graph page will display an error message.
Thanks to Jake for this one.

Updated the Results and enabled selection (Ctrl-A) and copy (Ctrl-C) functionality.

Corrected the axis display to clearly show when the data file axis differed from the current settings.

Added a "Point to line" function to the Tools -> Misc to check if three points are co-linear.
Updated the CAD2Susprog tool to correctly show the item captions and defaulted all numeric inputs to use the number of decimal places setting.
Thanks to Jay for these.

Updated all the FileRead DLLs to link through the portal axle data.
Thanks to Jan for these.

Updated the CAD2Susprog tool to correctly show the spindle length.

Updated all the Geometry -> Upright and Geometry -> Strut inputs with updated captions, fixed the graphic display when using inch measurements, and deleted the input for the spindle reference.
The spindle reference point was a redundant input, and was not used for any calculations.

Corrected the suspension link calculations to correctly handle calculating the square root of a negative number rather than raising an exception and causing the calculations to fail.
Thanks to Jesse for this one.
