Add Message.FromCurve that can take any Curve including Line, Polyline, etc.

[DmytroMuravskyi]

BACKGROUND:

• I needed a way to visualize a warning related to a polyline but there was only a way to do it for a single line. After inspecting the code I realized that one function can handle both line and polyline

DESCRIPTION:

• Added Message.FromCurve: much simpler function that takes both line and polyline.
• Message.FromLine is set obsolete.

TESTING:

• No test were added as Message class is about representation and not covered by unit tests.

REQUIRED:

• All changes are up to date in CHANGELOG.md.

COMMENTS:

• Any other notes.
