[BISERVER-8247] IE10 does not display the Login page correctly
* Changed dynamic script and link tags injection from using the document.write method to using the createElement/insertBefore method.
* Strangely, these document.write's didn't work in IE10, possibly it has to do with nesting level limits (the scripts where the document.write commands were issued were themselves already the product of dynamic script inclusion through document.write...)

BISERVER-8785 Fix update blockout periods from UI issue with selection.
BISERVER-6875 SecurityHelper.runAsUnauthenticated should run with a non-null Authentication instance: AnonymousAuthenticationToken

Action-based security needs a non-null Authentication. So instead of doing SecurityContextHolder.clearContext() which nulls out the Authentication, do SecurityContextHolder.getContext().setAuthentication(AnonymousAuthenticationToken).
This is harder than it needs to be because of the lack of availability of THE anonymous user and role names from the Spring application context.
Also, rename the method to runAsAnonymous.
BISERVER-8786 Allow non-admin to get list of schedule blockouts.
