Snap!

* Moves selected or all vertices of one or more objects to nearby vertices or grid points
* You can snap multiple selected objects with one click
* Only snaps to and from Editable Poly or Editable Mesh objects, other types are disregarded
* You can filter out hidden, frozen or currently selected objects to gain snap speed on larger scenes
* Use the "selected" flag to keep objects apart when snapping multiple ojects
* Added axis constraints
* Lower seek distance speeds up large snap selections in large scenes
* Infinite snap will try to snap to any valid point at any distance, its slow on large complex scenes
* Remove debug snap seek box visualisation to gain speed, it disables screen redraw
