Right mouse click behavior - while using Draw and Measurement tools

[oren-ned]

Right moues click is still working while Draw and Measurement tools are in use. Right mouse button opens content menu and also works as left click.

Suggestion: Left click can be configured to cancel the current Drawing Tool action and the RED x can button can be removed from Draw tool bar.
