Fixed the translate tool.
Fixed extrude bugs: fixed extrude reference disappearing shape at Escape, fixed a bug that sometimes the reference shape is not hidden.
Finalized the orthogonal rectangle drawing tool including the property grid, editing container and constraint.
Added an improvement that when the Sketcher tool is launched on a surface and the shape is rotated parallel with the screen also the drawing is blocked on that plane. Simulates a kind of 2D sketching.
