Columnresizer: resize-handle in touch mode too far to the left

[erikvandeven]

In touch mode, the dgrid-resize-handle is wider than normal. Since it is rendered to the left, it's not really on top of the actual column splitter. Proposed change is to correct the position for the larger resize-handle e.g.
html.has-touch .dgrid-resize-handle { border-left: 20px solid transparent; **right:-19px;** }
See the chrome debugger snapshot how the handle covers the dropdown we've created. Note we added padding of 5px in the header content.
