Improvements

• End supports now show their support width in the beam drawing, as interior supports do.
• Spring end supports now show a vertical spring, a rotational spring, or both, matching the stiffnesses entered.

Bug Fixes

• Fixed an issue where a fixed support at the right end of the beam could be partly cut off in the drawing.
• Fixed an issue where removing the last span could replace the beam's end support with an interior hinge, showing repeated error messages.
• Fixed a rare issue where edits to a value in tables could be refused and show an error message.
• Fixed an issue where opening a file that is not a Beam project from Windows Explorer showed a startup error and closed the application.
