shrink-wrap constraint, improve and remove some limitations.

- ability to change the space the axis is projected in (so you can choose worldspace or -space, was always local-space before).
- support projecting on a negative axis, without this some very simple clamping is not possible if the direction happened not to be positive.
- add distance limit (same as modifier), without this single meshes surrounding an object would make the constraint impossible to use in some cases (it would snap to the wrong side).

note: this removes the ability to project on multiple axes at once but this option only added up directions and didnt project on multiple axes as you might expect.
