DRY up the calculation of viewportW, and allow a manual setting of it if it's known
Expose a .getId() method, which allows a consumer to get the uid of the slick grid instance they're working with. Useful for managing multiple instances on a single page.
Added features to `setColumns`. It triggers a new event called `onColumnsChanged`. You can pass options that will be sent to your event handlers.
.resizeCanvas supports an option to specify a width and skip height calculation. Useful perf boost if you know the width and that only that changed.
trigger `onColumnsResized` whenever the width of them changes (e.g.: calculated that content should grow them), not just when the user drags to resize.
