Title: Fix video invalidation by full search on disk for each topic load.

Fixes #838

There were two issues; one was fixed previously, catching the second here:
* Need to check all videos for any updates, on each (non-cached) topic page load
* `stamp_video_counts` works recursively, and needed to propagate all input flags to all recursive calls.
