Add configurable timestamp sorting

Hi, Ive been looking into and playing around with the stand alone Aspire Dashboard, and its looking and working great.

My only current gripe is that (at least for the structured logs) they are sorted by timestamps ascending. ( oldest first ). this is a bit of a pain point, as I am constantly having to scroll down to the bottom to see the latest logs, as I am mostly interested in the _newest_ logs first (descending order).

It doesnt seem like any of the columns are sortable on the structed log data grid, and i would love an option to either add sorting to the columns, or at least have a configurable option to have the default sort be newest first.

Thanks!
