Shareable URLs for library components and searches

[bradenmacdonald]

As an author working with content libraries, I want to easily share any component in a library with other people on my team, by copying the URL from my browser and sending it to them.

As an author working with content libraries, I want to easily share any search results with other people on my team, by copying the URL from my browser and sending it to them.

As an author working with content libraries, I want to bookmark a search in my browser and return to it at any time, with the same filters and keywords applied.

As an author of a content library with public read access, I want to easily share any component in a library with any authors on the same Open edX instance, by copying the URL from my browser and sending it to them.

Update the router for content libraries v2 so that:

1. Filters (e.g. type, tags, and keywords) are reflected in the URL. Changes to the search parameters should replace the current URL, so that pressing back will go to the previous page rather than just undoing the last filter (which would be really annoying if you try to go back after changing the filters/keywords many times).
2. The sidebar is also reflected in the URL, including the current tab if applicable.
3. It should be possible to send a link to the "manage team" page.

Example (it doesn't have to use this exact format though): http://apps.local.openedx.io:2001/authoring/library/lib:OpenCraftX:ALPHA/collection/c-123/?type=text,problem&q=keyword&tags=foo,bar&sidebar=collection&sidebar_collection_id=c-123&sidebar_tab=details

With this example, changes to the query string should be done by replacing the current location (not added to history, not affecting the back button), and changes to the non-query string part should be done by updating the location (added to history, will integrate with back button).
