* When IPS4 (e.g. LL) sites based on CEF fail to validate, they no longer hang the app
* If a IPS4 CEF site throws a 503, or 400 error, retry
* Clean out the cookies during IPS4 CEF downloads so that they don't cause 400 errors
* Limit the number of connections to IPS4 sites to 20 per minute (one per 6 seconds)
* If a site *does* timeout, throw a log of the CEF state into `CEFStates` for easier debugging by the WJ team
* Wrote a new CLI utility to stress test the Verification routines.
* Ignore files that have `\Edit Scripts\Export\` in their path
There's sort of a theoretical disagreement, still. Should a failed download throw an exception, or return false? Users of this function still need to handle/prep for either/or.
Still, this is better than before, where some failures were being swallowed completely
