QuickGrid: simplify localizing pagination

[SteveSandersonMS]

Update: It's all covered except for localization of pagination. It's already possible to do that today by creating a custom paginator (and only 10 or so lines of code) but that's still harder than people would ideally want.

High priority

• On iOS Safari, column options can't be dismissed by tapping on the background. Try listening to touchstart (or similar) as well as click events.
• On iOS Safari, the sort indicators don't display at all because they use an unsupported unicode character. Try replacing these with SVG images.
• Default sort order is only applied if the data source is loaded asynchronously

Lower priority

• On iOS Safari, the pagination buttons don't look great because the unicode characters aren't exactly aligned with each other. Try replacing these with SVG images.
• On iOS Safari, there's no way to resize columns. Consider applying support for all the touch events for dragging.
• No built-in localization of the built-in strings ("Next page" in alt text, "14 items", etc.). Developers wanting to customize this have to override the pagination output.
• The built-in English text for pagination summary doesn't pluralize correctly ("1 items")

Most are now fixed in aspnet/AspLabs#520
