Version 247:

* The timeline now shows alert thumbnails when zoomed in near the limit.  This is configurable via `UI Settings` > `Timeline` where the zoom limits can be adjusted and thumbnails can be enabled for group timeline views if desired.
* Refactored thumbnail URL generation code to be simpler and not include unnecessary '.bvr' file extensions or '?' characters when there are no query string parameters.
* Rewrote async thumbnail loader to be more robust for the sake of the timeline thumbnail loader.
* Added Queue.removeAll method which takes a function to decide which elements to remove.
