Changes between Initial Version and Version 1 of Ticket #24425, comment 14

initial	v1
1	1	[attachment:24425.history-debounce.diff 24425.history-debounce.diff]
2	2
3		The URL updating on mouse drag was massively slowing things down. This patch makes a debounced function (250ms currently), and then only calls that from a custom event that fires after the diff has rendered (diff rendering has its own throttling built in, so this will filter out diffId changes that happen so quickly that by the time they start to render, the diffId has already changed.

5	5	Also a little bit of cleanup, removing unnecessary variables, and moving the Router to get passed in a model, instead of the set-it-after thing that was happening.
