add new vertex slide transform operator, different from the existing vertex slide tool based on user feedback.

- no 2-step select edge, then slide.  Instead you can slide and select the edge at the same time.
- ability to slide multiple verts at one.

supports proportional option for vertex slide and flipping, both matching edge slide functionality.
