Add drop object along a path with automatic trim.

1. The object can be a selection before or after selecting the tool, an entity or a block.

2. The path can be another entity from a start point to an end point.

3. Dropping can be made on one side or the other (like in other tools depending on the side of the cursor), with a choice of miroring the object or not.

4. The number of drops or the distance between can be selected.

5. The distance can be between a control point of the object or its sysmetry axis or border.

6. The dropping direction can be selected too.

7. The droping depth can be constrained : all control points have passed the path, or one of them. Alternatively, replace control points by an entity belonging to the object.

Exemple of use case : equidistant drills in a curved rail. The dropping depth constraint enables for example to ensure a drill has a minimal depth when not orthogonal to a plan.
