Allows users to conduct global search via the URL

[whitdog47]

This PR adds the global search query to the URL, providing a way to copy & paste the search query, and allowing direct access to search results via URL. For instance, https://dispatch.com/org/search/results?q=281 will show the search results for the query "281".

Thoughts on using a query param here? When I think of a search query I typically think of something like /search?q=foo mostly because I'd expect the result to be dynamic. Where as if it's directly in the URL id expect the results to be the same every time.

Thanks for the suggestion, @kevgliss. I changed to a query parameter and improved further by updating the URL bar and search results when user types in the inputbox.
