8.2.1 - 'Things we forgot to port' release

Patch release - consisting mainly of things we didn't port across from the v4 release of uSync, but its since turned out people would like 😃 with extra fixes by @JoseMarcenaro ✋

Updates:

#42 Web.Config override: put some settings in the web.config to override the usync8.config file
#41 Bulk Events: events that fire before and after uSync runs.
#18 Updates to Bulk Save mode: To reduce restart potential with ModelsBuilder in PureLive (not a complete fix)

Fix:

#35 uSync shows angular: if you override the default JSON casing behaviour in your site, some usync dashboard things fail.
#44 Fix Structure items order by Alias - broken when Export On Save - @JoseMarcenaro
#43 Fix version description when no add-ons present - @JoseMarcenaro

Known Issues :

You still may encounter site restarts and incomplete behaviour if you are running Models Builder in PureLive modes and a sync contains too many changes (see #18 for discussion on this).
